Ugh. I can't believe I fell victim to this. I thought I did everything right.
I made sure that my preferences were to NOT be billed in my home currency on my Wizard profile months ago. (though when I go back to try to check it, even after pressing EDIT on my credit card profile, it doesn't give me the same options to opt-out of DCC anymore?)
My contract printed out with the standard, "I had the option to be billed in GBP, but I chose to be billed in USD. SIGNATURE ON FILE". Which I promptly told the agent I didn't agree with. She typed something into her computer and said it was fixed.
When I returned to the counter to drop it off, I confirmed I was being billed in GBP and she confirmed it. My receipt is in GBP.
But, on my credit card statement, they billed it in USD. When I called AVIS International Customer Service, they said there was nothing they could do. That my signature on file said I had agreed to the conversion. I told them my profile specifically said not to, and I told the agent picking it up and dropping it off to bill in British Pounds. The phone rep said I would have to opt out of the preferred program in order to avoid the auto conversion; that because I was preferred the contracts are generated automatically that way.
w.t.f?!
