OP update here. My plot thickened. Here is a summary:
- Originally called on 1/14. Was assured that if I ordered that day, I would have THROUGH the following Saturday to configure and/or cancel the order with a full deposit refund. I specifically remember this because I originally called to clarify a few questions before ordering 1/15, the last day to get a deposit in and be confirmed for free SC charging for life. The rep basically said "Might as well do it now." because I would have through the 21st. I went ahead with the deposit. I have the name of the rep I talked with.
- 1/16. Test drove Model X. Once again, I specifically asked how long the configuration window was. Was assured again through the following Saturday. Worked with a different rep, who I also have the name of.
- 1/20. 100D option introduced by Tesla. That is what prompted me to start this thread.
- 1/21. With great feedback from this forum, decided to cancel the $2500 MX 90D "free life SC" deposit AND order and relax a while while I configured a 100D. I phoned the number as instructed here. The Tesla employee (yet a different person, who I also have the name of) I talked with politely accepted my cancellation. I specifically asked if it would in fact be cancelled since he was the nth person I'd talked to and he assured me it would be. He said not to be alarmed by any email notifications I would receive on Sunday confirming the order and that he would notify the showroom from which I placed the order and they would contact me early in the week. He specifically mentioned yet another Tesla rep, since my test-drive rep was on vacation.
- As of yesterday, 1/27, I was getting suspicious after not hearing from the showroom. I called today and was told the order was not cancelled "But they would be flexible and allow me to still change the order without incurring any additional penalties."
Ok. This pissed me off and on principle alone makes me want to flat out cancel or at least wait until the full $2500 deposit is refunded before making any other decisions. A couple of email exchanges repeated essentially the same thing. "The order wasn't cancelled but we will do you a favor...". Now they are pressuring me to complete the order switch to the 100D "because time is of the essence". Which, again, I had planned on all along BUT I am highly averse to being told I am wrong on something I am certain I am right. I am in absolute no hurry to order the Tesla. The only reason I was previously was because of the "free charging for life" window closing. After I cancelled the order on 1/21, I was thinking I would take a couple of mentally-comfortable weeks to weigh options. I really think something was dropped between the multiple respectively-low Tesla employees I worked with.
Should I fight it? Just settle? FWIW, if anyone else cancels within their "configuration window" get all kinds of names and written confirmation.
