If this is a used unit, hang in there but keep calling/visiting and pushing. This should be a slower time for them to get the job done. Are you having major things done to it? If so, perhaps that's the hang-up.
After you receive it and agree to what was done, enjoy the heck out of it.
If you then have future repairs to be made, that doesn't involve the original purchase, move to another repair facility. You have no obligation to keep returning to the same dealer - unless it's for something that should have been corrected in the first place. Good luck!
