Frustration - *****ing my money

Despite complaints on Hello Peter, personal visit to Customer Centre and numerous phone calls and e-mails I am still waiting for someone from Vodacom to sort out my account. For over 6 months now they have been over-billing me, *****ing my money and despite proof of returned hand sets I still cant get them to sort it out. And once I log this complaint I will get an automated response saying someone will contact me... utter **** this is now the 2nd time I have complained on Hello Peter and I am still waiting for someone to call me and sort it out. I am now so frustrated that when my contract ends I will cancel with Vodacom and go to another provider as it seems to be the only way I can stop them taking money of my account *******ly because NOBODY AT VODACOM GIVES A **** !!!!!!!!!!!
