No response but double debit

I received an email informing me that you will be double debitting me this month because you did not debit me last month but you never addressed my double debit of July 26 2015. Please advise why that issue was clearly ignored but yet you have the guts to tell me you will be double debitting me. You guys suck, you have absolutely no customer service, you work like a dictator-communication is one way ONLY! This is probably my forth complaint about the same issue and yet nothing gets done. Do you guys think I don't care about my money????
