U.S. Bancorp Prepaid Card Complaint

U.S. Bancorp Prepaid card department,

General purpose card Unauthorized transactions/trans. issues Washington

I purchased 2 $200.00 Mastercard gift cards from - on -/-/2016. When I attempted to use the cards a few weeks later, I found one had $45.00 left and the other $35.00. So on one card there is a fraudulent charge of $150.00 and on the other, $160.00. I called US Bank 's fraud hotline in -/-/2016 and they sent me new cards with the current balances on it and told me I would get the fraudulent amount credited back with in 4 weeks. Since then, I still have not gotten the fraudulent amounts refunded back to me and US Bank refuses to help.
