Unicoop Firenze

A couple weeks ago I went to the grocery store to buy groceries (obviously.) The machine was giving me trouble. It wouldn't accept my credit card, which I tried several times. Then I tried my debit card, but that was also refused. It finally accepted my credit card. So I just found out that they charged me on both cards. I need to go to Coop and try and explain to them that they need to reverse one of the charges. How fun will that be? Little Italian combined with Little English = for the win. Er... not really. This is going to be awful. I might just go in with a statement already written and hand it over.
