ok, I took delivery of my refresh model s a month ago. I financed. On delivery, the delivery specialist looked up my payments and deposit from my credit union, and it showed my balance as zero. My tesla account online also read as balance zero, and the car showed as delivered. I drove the car home. Now one month later I get an email from my delivery specialist that I never gave them a check for $10,000 which was what he said we agreed to and he had my tesla opened back up to reflect a payment deficit of $10,000 and when do I plan on paying this. My response was that I took possession already, and they told me it was balance of zero, and that no car company would allow anyone to take possession of a car without full payment. He said that they submit the papers to California, and then the finance department found this "descrepancy". As it is now a month later, that money isn't readily available. Does anyone have any thoughts about this? If it turns out that it was a shortfall in payment due to their mistake, but they delivered, and now a month later they want more money, how should I proceed.
