<prompt> Human: Basically, Ive never disputed a credit card charge until now. Was at a big birthday dinner out of town with some friends and we split the bill 5 way, each one was a little different, pretty easy for the staff to do. BIGGEST MISTAKE I made was not saving the signed version of the receipt. In the next 2-3 days, I see 5 charges appear on my card pending, one of them is the correct amount. I figure I give it a day before I investigate further. Next day, the 4 charges disappear and I am left with one incorrect charge for about 120 more than I signed for.I contact restaurant, they are slow to respond. I escalate a bit and they provide a print out showing all these things I never ordered. Basically a screen shot from a point of sale unit. No receipts or anything.I dispute charge with Chase. Now about 2 months later, they are telling me that I cant prove otherwise, and I lost. The restaurant cannot show any other evidence or a signed receipt.I am wrong to think that this is bad evidence? They are not providing any signed receipt or anything with my signature authorizing the charge. I thought that this is why merchants always kept the receipts in the cash drawers.Any one have thoughts on this? Sorry for the ramble, but 100 is a bit of money. Assistant: If I were in your position, I would probably keep calling Chase until you get a decent service rep and ask if there is an appeals process to challenge this decision. Alternatively, you could pay the credit card bill and try to take the restaurant to small claims court to recover your 100. Its possible the restaurant wont send anyone to the courthouse, and you will win on default judgement. That alternative is probably better suited for rlegaladvice though.If all else fails, pay the 100, and stop using Chase. There are plenty of alternatives for credit cards. Amex has a good reputation for disputes like this.Human: I would definitely do small claims if it was local. I think my only last real weapon is calling up the place again and threatening some bad online reviews? The place is also part of a national chain, might also be worthwhile telling them I will call corporate.Hate to be a dick, but it kind of pisses me off.  <response>: They stole from you. Youre not being a dick. Definitely call corporate and report the situation. Be polite but firm. Explain what happened and exactly how youd like it resolved. Also, you can try send an email to consumerist.comconsumerist.com. They live for stories like this, and they love to embarrass shady companies with bad publicity. Dont bother threatening bad reviews. The low-level employee you will be threatening doesnt give a crap.
