Hey I'm currently trying to get my money back from a bar in London aswell (maybe the same 1?), i got double charged for an already expensive meal. I made the initial payment on a chip an pin machine, but after checking the amount and entering my pin they realized their was no receipt paper left in it. An acting manager came over with another chip n pin machine and ensured me the previous one wouldn't have processed the payment. One week later and I have two identical charges on my statement.... they keep giving me broken promises now about reimbursing the money back to my account now. My bank can't do anything because it was on debit card/ What was the bar you were at? Was it the No1 leicester Square.?.. because they have been very unprofessional with me.
