Vodacom service pathetic

I tried to upgrade one of my contracts but apparently my account is flagged for *****. Nobody but nobody knows how to remove this flag. I went to the Vodacom shop 3 times they called the ***** department who told them to call some other department only to be told again to call the ***** department. I never flagged the ***** so I have no idea why my account is blocked. I then call the Client Care Centre and speak to Ntebaleng who apparently is not allowed to give me her surname. She did not help me and just insisted I go back to the store. Your service is pathetic and I am seriously considering never taking a contract with you ever again. How is it the nobody knows how to remove the flag. Apparently the client needs to go to a shop with his/her ID document to be verified, which I did 3 times. And the worst is it doesn't seem as if any of your employees care, they just very blasé about this whole thing because it doesn't affect them. I have been a Vodacom customer for years and every week I get calls to purchase this or that. Please don't ever call me again because its fine to deduct my money every month but you don't care about your customers.
