Over charging and no response to complaints

Just over a month ago I noticed an over charge of R 4 000 on my account. I immediately contacted Vodacom customer service and laid a dispute on my bill. When a returned home I went to my Knysna Branch where they assisted me in ensuring the complaint was submitted. They also informed me that according to the note on the system the problem must be resolved by 4th of May. <br> <br> I have been back to my branch where they have resubmitted my dispute twice (separate days) and was told that within 4 hours (on each occasion) I will have someone contact me, on both occasions no one called me back!!!!! <br> <br> I have also asked for itemised billing to be sent to me, that has not been done either!!<br> <br> To rub salt further into the wound, my service got suspended due to not paying the over charge. I was told i have to pay this then they will refund me later once they resolve the dispute!!! Funny aren't you!<br> <br> If I don't have a satisfactory resolution to this problem by tomorrow afternoon, I'm taking this matter to ICASA (not a thread, but a promise). Vodacom is quick to up our subscription in the middle of a contract, but cant have the decency to speak to its clients!!!!<br>
