either somehow someone got your credit card number or fraud
that doesn't make sense, though. in order for a chargeback to happen at all, there would have needed to be the charge in the first place. I've never had $50 or $56 deposited into my account before, definitely the bank would know something was up if someone ordered a chargeback on an account that hadn't charged anyone. my guess is that my bank made a mistake
fake edit: apparently I actually deposited exactly $56 on november 26. long before this happened
still gonna call my bank, though
