You pay or you don't pay makes no difference

I have been trying to grt some assistance from Tyme bank for 2 months now and i am npt getting any joy from it. I have loan account with them and for the past 2 months they have debited and amount that is 1 cent short amd i keep on receiving messages that my account is in arrears with that amoumt, i habe sent several messages pleading with them to fix this as it has a negative impact on my credit score but they don't care. Last month one of their consultants phoned me and they said the error is on their side and they will fix it but i am still experiencing the same problem that i experienced last month, it has not been fixed. No one answers their phone call no and even writing an email does not help. The last email i wrote the reply was a statement showing i still owe that one cent, how can your system debit money and be once cent short amd then you keep on sending me messages as if it's my fault. I hate receiving these messages because i have paid. Tymebank has left a bad taste in my mouth
