Hold on a minute. You took your car into a dealer to get a key made and to fix the top or just to get a key made? Did you give them permission to work on the top? if they were not authorized to work on the top, then you know who should be fixing your car!!! THE DEALER! I would be upset! Those parts will be hard to get if you do happen to find them They will be expensive!
Good .luck (hire a lawyer and have them write a letter)
Glad to hear! Btw. Can you explain to the rest of us what he did that the rest could or did not do for you. I know he fixed you convert top but if you could be more specific i and many more would likely appreciate it.
