AGAIN, NO FEEDBAC****!!

I have now gone and paid the wrong amount for the month of October due by 1st November. I had a bad review on Hello Peter for R187 which was TOTALLY incorrect which showed on my MY VODACOM. A lady by the name of Lesley Abels from your website team assisted me and credited this amount against my account. I then logged back onto my MY VODACOM and saw that the amount went from R187 in arrears (which is what she credited me for) to R889. I have NEVER missed a payment so where did this amount come from? Your systems are completely inaccurate. So i emailed her back to ask what this was and asked if this was my instalment which is only due on 1st November with NO reply (as per usual). I also commmented on my previous review to ask for somebody to get back to me with NO reply. I then assumed this was my instalment due 1st November and have now paid this. Because i am new to MY VODACOM i dont really know how it works so i took the time to look around and found that i have now paid the wrong invoice amount. I DO NOT HAVE ANY PAYMENTS OUTSTANDING WITH YOU!!! If i did, they would have been on my case (like they were for a little R187) constantly!! They would have harassed me like they did for the R187. I also requested that my name be cleared with ITC and confirmed with me in writing. NOTHING has been done. My contract is due for an upgrade soon and i will NOT be renewing with you at this rate. I am completely disappointed with the bad service and system that Vodacom chooses to operate with!!! I NEED FEEDBACK TODAY!! I have spent enough time, petrol and energy on trying to correct this when it isnt my job to do so. That is why i have a SERVICE provider!!!!
