USAA Savings Credit Card Complaint

USAA Savings Credit card department,

Billing disputes Illinois

I disputed a transaction on my USAA Master Card and they took charges off. They Merchant responded and they reissued him the monies even though I have resubmitted more evidnce showing substandard work and misleading representation to Emissions they will not take the monies off because they do n't have a letter from a third party even thought they have the problem on the receipt. They are letting - - - get away with fraudulent business practices at my expense.
