<prompt> Human: Same amount appeared 3 days apart from a shop I only went to once this month. They mentioned they were having some technical difficulties with their card reader when I came in, so Im guessing this was the culprit.I havent received my final statement for the month, so Im hoping the second one will be gone by the time I get it. But if not, how should I proceed? Im guessing I need to call the credit card company and dispute it, but Ive heard that just because the CC company removes the charge, it doesnt mean Im off the hook for paying it. Do I also need to contact the business the charge came from and have them look into it?Thanks!EDIT: So, the evening news came up with this: At least it appears like the problem with correct itself. Thanks for all the help!  <response>: Call the shop right now and get them to fix it. If by the time your statement comes and it is still there, call the CC company and dispute. Ask how much you need to pay. Usually you do not have to pay the disputed amount during the investigation.
