AmpOn.com/BillEAWDate review: Unknown charges

On August 16 I was charged $119.82 also a charge of $13.08 to my debit credit card I have no idea what these charges are and I need to get to the bottom of it I did not authorize any charges except for one that was in the amount of $68 and some changes would greatly appreciate either a call back or a text from your chat room to find out what is going on with my account otherwise I will be canceling my Amazon Prime and I will turn this into my bank
