Capital One Bank Account Or Service Complaint

Capital One Bank account or service department,

Other bank product/service Account opening, closing, or management Ohio

I have a credit card with Capital One, a gm card to be precise. Before - I ordered some vinyl upholstery from - -, after receiving notice that the order had been delivered, but not received by me I complained to Capital One. They arbitrated an agreement with - - to reissue the order, - - would not send the order until they got the cash back from Capital One. After another long wait I cancelled the order, and - - told me there would be no refund because they never received the money from Capital one. I have been waiting months to see a refund, and finally filed a complaint, they tell me they ca n't help me. I have no product, but am still out the money plus interest charged on my original complaint.
