Incapable staff at Rain

I have a month to month contract with Rain. When they do not receive payment they stop my service and I am ok with that. Last December I moved house. I received an sms payment was not received and I was not receiving their service. Which I was happy with. Now they keep trying to deduct R1300 from my bank account which I did not authorise! When I called the call centre they say my service was not suspended even though they did not receive my payment which is nonsense because I did not use it for the last couple of months! Just because someone on yoyr side did not do their job and suspend my account like you smsed me saying you did...why is that my problem now?! Stop trying to debit my account. You people sent me a message stating no payment no service so why bill me for months on end and try to ***** from my bank account? Month to month means to bill and pay per month. Understand that. Also do not sms me silly words. Email me a proper response!
