I need proof of Account Statement

I have an account with Autopage for about 15 years, they used to send me the bill or account through my box number at post office and we changed to email address. last year they stop sending the bill through my email and also to my box without telling me. I tried to call them several times to fixed this problem,nothing happened but they do deduct their amount from my account without know how much I suppose to pay to them. I stopped paying this account since I don't trust this debit issues without sending me the statement. As per our agreement we did from the start ,they should send me the statement and also communicate with me if ever they are some changes ,that will affect my agreement with them. All I want is a proof of how much I owe Autopage every month
