Pathetic service from Vodacom

I can not believe what *********** people you have working there. 1. I called every month for the past 4 months very patiently to get my CONTRACT cancelled with you (NOT MY SIM CARD). I was either told that I called after the deadline or I called too early! 2. I have been debited a further 2 months after finally cancelling my contract After calling to query these debits I have received no feedback nor have I received my money back. 3. Today Vodacom went ahead and cancelled my Sim card which is my primary number! 4. I have no form of communication, nor can I use my banking services, since they are all linked to my number, and I am told that it will take up to 7 working days to re-activate?? Do you suggest I get people trying to contact me to write me letters? I also find it extremely painful to spend my time listening to your hundred's of prompts before I am finally put through to one of your call center agents that could not help solve my problem anyway. So disappointed!
