I did a trade in Saturday and Tesla owes me around $11,500. I was signing documents and one had all the info on it but they didn't give me a copy. I don't see it on my Tesla account either. My delivery specialist is not responding to my questions. Should I be worried? I don't want to wait 30-60 days hoping I get a check and then not get it with no proof that I am suppose to get it. Has anyone had a trade in where Tesla owed them money?
