Chase Bank is a Rip-Off

I ordered 2 New Cell phone batteries on the internet. The merchant sent me two very used batteries. The ole BAIT AND SWITCH Routine. I returned them USPS with Confirmation Received Receipt and the merchant won't refund or send new ones. I sent all the proof to CHASE. They send a letter back stating "Regretfully, it does not qualify as a billing error or quality dispute against the merchant, which limits our ability to assist you".... Well if sending used merchandise as new is not a quality dispute - then I take it that CHASE has an excuse FOR NEVER DISPUTING ANY CHARGES!.... I've since gotton rid of all my Chase cards and advise everyone to do the same - unless you don't mind chancing GETTING RIPPED-OFF BY CHASE VISA.......
