I made a purchase online using my debit card which was linked to my XXXX account. When I received the item it was not an authentic item. I tried reaching the seller and got no response. I called XXXX and they informed me to call the bank as they were not the funding source. I called the bank and disputed charge and was informed via phone and mail that I can not be helped and they were sorry I have to get a hold of the seller.
