Poor performance

On the 17 March 2015 i received a sms from Autopage saying that my account is behind and i need to make a payment that day to avoid my cellphone to be barred. I phone customer services and spoke to Shelly and explained to her that a payment was made. i dont understand.( I do cash or EFT payments and use my cell number as reference.) I told her i am going to go check on the bank and will get back to her. ( my sister paid EFT the payment from her account) This is how i found out that she paid it into the old Nasuha account.( Was paid in on the 9 March R500) I phoned Shelly and told her that i found the problem and asked her to give me the right banking details so that i can EFT the payment. I EFT R500 on the 18 March. I also asked her not to barre my cell.it was barred.Phoned in again and spoke to Stans about my story and told me that he will retrieve the R500 from Nashau. My cell was barres 5 time. I phoned in 6 times. i then told Stans that ill make another Payment of R500. phone still barred. No i see that they wanna charge me from Dec now. I have always made my payment. Garth at zewenwaght mall was no help.YOU ARE USELESS!!! i will not pay one more send
