JPMorgan Chase Bank Account Or Service Complaint

JPMorgan Chase Bank account or service department,

Other bank product/service Using a debit or ATM card Ohio

Bought a product from a company and recieved it well after they originally told me. Product did n't work, so I sent it back per a text agreement with the merchant. Merchant ignored me and would not respond to me for over a month. Decided to get my bank involved, they sent me temporary funds only to take them back a few weeks later saying it was more than 60 days after my purchase while 20+ days I did n't have the product delivered to me. Now as of yesterday the merchant has finally responded to me basically saying they have the manifold and the money and then will not contact me anymore. My bank will not do anything even with written proof the company has the product and does n't plan on sending it back to me.
