A horrible story, but it would be nice if you could fill in some of the missing pieces. If they couldn't fix it how did you get back on the road to get home? Did they agree to invoice you, our did you have to make a payment? If you paid by credit card you can contest the charges. If you paid by check you can stop payment on the check. I wonder because we seldom have a check on hand when we travel, probably never, and we don't travel with a lot of cash, certainly not $700, so if assistance were to be needed requiring a payment we would be SOL (totally out of luck). Glad you made it home safely, and hope this business dispute can be resolved to your satisfaction.
