I. M on year number 3 renewal. I have been giving this as a gift and have explained this every time. I wanted two pay for a couple years at a time, no I can't do that. I have asked for paper billing no auto renew. Every year you start tapping my credit card after I said no to auto billing. What really gets me the amount on monthly credit card was twice the amount that I had agreed to, with out any notice. This is in no way good customer service
