Double Payment Taken yet Service Suspended for "none" Payment

Hi MTN ZA can anyone (preferably a human) from your contract billing department please get in touch with me as my bank statements clearly show payments successfully made every month however your latest statement received for the month of May (Also 1st statement received in four months) indicates that no payments have been made and that I am in arrears resulting in my service being suspended......upon confirming all payments via my bank I have noticed that not only have I NOT missed a single payment in Feb you decided to double charge me and take the money - I please need clarification and my service reactivated as soon as possible.
