VODACOM TERRIBLE SERVICE

I am super unhappy with the service I have been recieving from vodacom at this point in time. On the 20th of june I went into the store to get a change of ownership done on my number from my parents name to mine. At that date our account was behind in payments, we paid the account on the day. The consultant then submitted the paper work for everything on the monday when the payment cleared. Vodacom denied my transfer request because I recently opened a contract on my name not long before. This issue I completely understand. For the last 2 weeks i have been calling upgrades and cancellations department to do a upgrade on my number as I have been due for the last 8 months and because I cannot transfer my number, so this was the compromise we came to. Each and every time I phone I have to wait 30-50 minutes to get hold of a consultant only to be told that there is a problem with the account that it does not let them see what I qualify for. I have told them to escalate the problem and fix it ( a week ago) they did nothing. Then I get told I must wait till the 1st of july to do my upgrade , I was on the phone yesterday trying to sort the same issue out probably for about 6 hours. I still have not done any upgrade. I keep getting told by consultants that they will call me back and they are speaking to their higher up and I get no calls back. I am at the point where i am so frustrated with the level of service i have recieved which is the worst i have ever had from them and I've been with vodacom my whole life and so have my parents. At this point I want to just cancel my contract , revert to prepaid and go to another service provider because they can at least help me with what I need. All I need is for someone to sort my issue out immediately. Super fed up.
