I tried to cancel my order before it shipped, but MPB refused to do so and said I would have to refuse delivery or return the product for a refund. I refused delivery, but they didn't issue a refund, so I requested a chargeback with my credit card. Then they said they would issue a refund only if the chargeback were withdrawn, so I waited. They simultaneously objected to the chargeback, so the bank didn't complete the chargeback, but MPB still refused to issue a refund. I've been contacting customer service repeatedly to get the refund I'm owed, but they insist that I have to contact Citi and withdraw the dispute entirely, even though Citi has not paid the chargeback. It's fraudulent. They owe me over $1500 for products they acknowledge I returned but they are refusing to issue a refund and they convinced the bank not to do a chargeback, which at this point I am ALSO entitled to. I am on the verge of filing a police report, a BBB complaint, and taking whatever other measures are necessary to bring this to light and get my money back.
