I bought an item by mistake and sent it back unopened. Seller return$34 of the $495 and Amazon closed it as a full refund. Seller claims the item did not match serial number and refuses a full refund. Since I never opened this means Seller is selling refurbished items as new and is scamming people. Seller has the $495 dyson vacuum and my money 5 customer service reps have "filed an A-Z claim" on my behalf guaranteeing my refund, but each time I check on status the new rep tells me no claim was filed, and says they'll file one and not to worry, guaranteeing my refund, and again I contact to check and get the same thing. The seller continues to operate his scam store, has my money, has the item, and I have nothing. I have had almost $500 stolen from me trusting amazon services, and amazon refuses to help, and customer support os seemingly lying to me cycling the same words over and over,probably hoping I will give up. But this is not $20, this is $500. I do not have the option of filing a claim because the algorithm sees that I have recieved a refund and closed it as a full refund.. completely neglecting that it's far from a full refund
