12 months and waiting! Shocking customer service!

I am disappointed to have to write this review but I have been dealing with an incorrect contract and continuous mistakes by Vodacom since November last year. I have been over charged monthly and have had to go into the Westwood Mall store a few times a month to get feedback. I have been very patient and understanding while they tried to fix the issues, however this is now completely unacceptable. I need to be refunded the overcharged amount immediately not credited to my account. And want immediate cancellation of this account due the *********** customer service. A good idea would also be to reimburse me for all the times I've had to unnecessarily drive to the shop to get feedback. The staff are lovely and friendly in Westwood mall but the follow up and feedback almost nonexistent and the overall company's service is shocking. I have been with Vodacom for many many years but I am now ready to give up on this 'reliable' company. I am also still waiting for a 3gig bundle which has been promised to me however it is one more item on this list of unfulfilled promises from Vodacom that has not been seen to. I am bitterly disappointed. Hopefully the company will take some time to finally respond to me.
