[Resolved]  Amazon Mktplace Pmts Amzn Com Bill Wa — Unauthorized Charges to ATM Mastercard

I noticed (3) charges on my ATM Mastercard that I did not authorize in the amounts of ($7.71) on March 20, 2012, ($11.95) on March 19, 2012, and the 3rd charge was from AMAZON COM SEATTLE WA ($7.21) on March 19, 2012. Have had no way to contact the above company, so the bank needed to hot card my ATM card in order for the charges to stop. Please contact me in regard to how to handle this situation.
Thank You,
Kathryn A. Wolfe
