VERY BAD SERVICE

This is my second complaint. I did an upgrade on my phone phone number *** and my data stick ***. It has been more than a week and neither of them are working, I went to the Vodashop again today and they located the problem with my phone which after phoning Vodacom several times and even talking to the manager they could not figure out. My phone cannot receive or make phone calls or smses because of a call barring that was activated by Vodacom, when I try to remove the Call barring I'm given an error message stating that there is a SIM and MMI error. My data stick does not have any data loaded on it. I have phoned Vodacom countless times and even spoken to the manager, they never get back to me and are not doing anything about the problem. My last call to vadacom today I was told they cannot help me now I must wait until the end of the month. The lady at vodashop also phoned vodacom and they refused to help her sort out my problem. I am paying for a service I am not receiving.
