I did something similar. I was to take delivery of a model S 60 yesterday. Well the morning of this appointment I found out about the Firesale and found 3 cars identical to mine with 75 Kwh battery upgrade. for Basically $2,000.00 more. So I asked my DS to sell me my car with the 75 Kwh upgrade on it. He referred me back to the sales office cuase according to him he had no authority. The request went to the regional sales manager and they denied my request. They said I could buy the model S 75 but I would loose my deposit. Well that didn't set well with me. So I complained. Then two hours later they offered me to waive the destinatioon fees on the new 75, but again would keep my deposit. After a long and heated discussion, I finally told them to keep my deposit that if Tesla really thinks treating a customer like this is a good business move, I would rather drive a different car. I also told them I would not be silent about this treatment. Well about 15 minutes later I get a phone call and guess what no issues. Sure we can transfer your deposit towards the new 75 sorry it was a misunderstanding ( I think NOT) it was a greedy move by a regional manager.
