<prompt> Human: I ordered an item over the phone. We agreed on a price. I gave my debit card number over the phone. I sent an email detailing my order, and asking for a receipt, but I forgot to include the price we agreed upon. The merchant charged me more than the agreed price, and then double-charged me on top of that in other words, two separate identical charges appeared on my statement. The never sent me a receipt, do not answer the phone, and do not respond to me emails. I disputed the charge with the bank and they are giving me the runaround. After almost a month, and pages and pages of documentation, the bank told me today they cannot submit the dispute. I waiting for a call back from someone else but in the meantime I dont understand whats happening here. I thought MastercardVisa handles this, not my bank. Also, I thought a debit run over the phone is basically a credit card since you dont enter your PIN. What else should I be doing? Is there a different course of action I should be taking?Edited for grammar and flair.Assistant: I had an issue similar to this. Merchant was no help, bank was no help. I filed a complaint with the Better Business Bureau and eventually was refunded. Human: I might do that if I cant get this straightened out.  <response>: BBB is a private for profit company whose business model is built around extorting businesses who have complaints filed against them. Aside from public shaming, the BBB has no actual power.WizardOfIf is absolutely correct. You should contact your states attorney general office and file a formal complaint. If it is a lot of money, sue them.
