BTW, it is a very good idea to file dispute charge against Tesla for unauthorized charge.
Each dispute, Tesla will get flagged by the major credit card companies. For each successful dispute, Tesla has to pay hefty penalty in addition to more expensive processing fee in future transaction. With enough incidents, this will definitely getting necessary attention. I had been dealing on both end as a vendor and as a customer. The last thing I want to do is to get disputed from the customers. I would rather give them full refund instead of filing rebuttal against the dispute.
While Tesla has a bigger financial team, filing rebuttal would still be a cost for them.
Anyway, for the large purchase I usually book keep all the email conversation, texts and screenshots with vendors -- as well as timeline of events -- in case anything go south, including taking my cars to service.
So far dealing with dispute on credit card purchase has been relatively hassle free and save my angry energy to something more meaningful.
