Okay folks, - here follows my little contribution to that topic.
The answer to the original question "Reporting of a Destination Charger Failure" (asked by
@Corazon) is simple. It is effectively the
Tesla driver / owner with his
Tesla app which has the only
reliable option in reporting a technical problem.
Yes, the functioning of the Destination Charger is the hotel's or Destination Charging locations responsibility. But in reality, the destination charging partner receives near no support if there exists a problem. I can confirm here my PAINFUL experience regarding our Tesla Destination Charging TWC issues.
I am located in Central Europe. And in summary, I have unfortunately to say that the support in conjunction with the Destination Charging Program is almost non-existent. At our small hotel company we have totally three (European type 2) Wall Connectors installed (three-phase, 22kw). Two of them are part of the Destination Charging program, the third was bought independently.
It turned out that we had TWC chargers from a problematic series (revision G and H) from
2016/2017. These TWC have problems with the cables - the wires tend to break quite easy. This is a known problem, at least for Europe. And it was also a problem for two of our TWC.
I first reported a TWC problem to the Tesla support in May 2020. The weeks passed and nothing happened. At the end of July I told a unhappy Tesla driver that he should make a report with his Tesla app. And you know what? At the end of the next day a Tesla employee came! He was responsible for the regional super charger infrastructure. Unfortunately he knows not a lot regarding the 2016/2017 TWC cable issues.
However, he came a day later again an looked deep into the TWC. He was all the time "guided" and strictly monitored by a Tesla "Sr. Field Support Engineer" (a women, but that is at this point irrelevant). As I mentioned, the problem was known. Well, it was known for me and my electrician but not for the Tesla guy and the Tesla "Sr. Field Support Engineer" lady. So the deplorable Tesla technician spent hours in measuring all different things at both buggy TWC. He was able to confirm that there were broken wires at both TWC charging cables. But it looks that this was not enough

, - it looks that the "Sr. Field Support Engineer" lady was on the search of "more".
Towards the evening when the Tesla technician guy was somehow "finished" (with his nerves) I asked him again regarding the status. During our short discussion I told him that the two faulty TWCs are connected together in load balancing (load sharing) configuration. He was for a moment somewhat surprised but the "Sr. Field Support Engineer" lady was for whatever reason "not excited". So, the deplorable Tesla technician left without having achieved a lot.
After a few days the "Sr. Field Support Engineer" lady phoned back. She really wanted that a local electrician makes the whole work a second time, under her monitoring.

My electrician said NO, I said also NO, because as I said the problem was clear. If she really want that someone will do that, she must send again the deplorable Tesla technician. Maybe this was the moment when I started taking the story personally...
After the Tesla support has led to almost nothing, I started asking all disappointed Tesla drivers to report the TWC problems via the Tesla app. And you know what? At the begging of the month of September I get a replacement TWC!

The second buggy TWC was separately replaced later (at our own expense). It no longer had any warranty because it was not part of the Destination Charging program.
So finally it must be said, - Tesla has to get in that topic much, much, MUCH better. This is not the kind of support you would expect from a company with such a reputation.
There was in the whole process so a lot of unnecessary overhead, of wasted energy. I was very sorry for the Tesla technician. He recognized the problem, but he was caught in a "static process flow" which is probably not even understood by Tesla itself. Maybe this was true also for the Tesla "Sr. Field Support Engineer" lady. It seems that the Tesla support staff are doing their job based on very very rigid, static procedures. A nightmare for me, - but that's a personal opinion.
Okay, what could be a better, a pragmatic (and cheap) solution for Tesla? For example, Tesla could provide (at least for their partners) a TWC "repair charging cable" kit. This will allow the Destination charging members to do effectively the job for Tesla. My electrician has told me several times that he can do that if he gets an original TWC charging cable replacement. Such replacement exists, but these are not available for external usage and are not distributed separately. (Tesla uses them internally to refurbish their TWC.)
Maybe this feedback will help some people here to understand the whole matter somewhat better and / or different. It shows pretty well where the problems are in the whole process.
Kind regards
