3 weeks later and nothing has been resolved

So after 3 weeks of complaining and waiting for Vodacom to sort out the problems l I have had, all I have received is call center agents saying that my issue has been escalated and the managers will have it sorted out the next day, promising to phone me back and never actually calling. I have been so disappointed with Vodacom's service that I asked for my contract to be canceled, yet after almost 2 weeks they cannot even do that. Come on Vodacom, wake the *** up and sort out this issue! I have seriously had enough of this now! Will never go back to Vodacom ever again!!!!
