No Vehicle

I reserved a car from Rent-A-Wreck Seattle in March for a two-week holiday in September 2008. I showed up at the airport in the evening (having flown from overseas) and called the number Rent-A-Wreck had given me for the free shuttle to collect my car. I was told that they had no vehicles so they could not honor the reservation I had made even though I had given them my credit card details and had a reservation number. I asked them what I should do and the man on the end of the line just kept repeating that he had no vehicles. I could try again the following day but as I needed transport to get from the airport to my motel for that night and to head north the following day at 6 am, I was forced to trawl the airport car rental counters, finally coming away with a minivan (for only two of us) for $175 more than my original quote from Rent-A-Wreck. Several days later, I did find out that they had called my home (we do not have cell phones) and let my mother know that a car had come back later that night but it was too late. I emailed Rent-A-Wreck to complain about their unreliability when we returned from holiday, but several weeks have gone by and there has been no response.
