I fell out big time with the AA a few years ago - long rant warning.
We were living in South Wales and just about to move up to the Wirral. Around September time the wife was heading over to home in Northern Ireland while house deals were being done and I was completing a course in Manchester for the new job and unfortunately she had a car crash in Liverpool on her way to the ferry (when it used to be in Bootle). Anyway, nice AA man turns up, loads what is left of her Ford Sierra onto a flat bed and takes it to Magherafelt over on the boat. We then move to the Wirral and renew membership in January.
Later I get a letter saying our AA membership has been suspended as we haven't paid the bill for the ferry.
Despite us telling the AA we moved and renewing the membership it seems some other department of the AA, after deciding we had to pay for the flat bed recovery wagon to have gone on the ferry (which was not mentioned at the time), had sent several demands for payment to our old address, none of which had been received. The first we heard of this was when we got a letter to the new address saying membership suspended. Anyway, wasn't happy but paid the not inconsiderable bill they said we owed them for the ferry and thought that would be the end of it.
Few months later was out at a MAG meeting in North Wales and got a puncture on my old Katana 650. No problem I thinks, just ring AA. However, operator says they will not send anyone out because I still haven't paid the bill for the ferry and therefore membership still suspended. I says no I paid the bill months ago. She says they won't send anyone out until I prove that the bill has been paid. I asked how exactly am I supposed to do that at the side of the road in North Wales at half eleven at night. Didn't matter, they still refused to help me. Luckily I had insurance with Carole Nash at the time so could use there breakdown cover to get me home.
After many more calls and correspondence the AA eventually admit that I had paid the bill and unsuspend my membership. However, they didn't even offer an apology, let alone any compensation for being left stranded.
After that defected to the RAC. However, they are a long way from perfect. One time broke down on the M2 by Templepatrick (in County Antrim) and after waiting for over two hours (and having clearly told them I was in NI) I rang again to discover that they had a poor bloke driving up and down the M2 in Kent looking for me!
