Vodacom treating my wife in an unacceptable manner

I've gone through the complaints listed here (hellopeter) against Vodacom and I can say I'm not surprised by the way they (Vodacom) has been treating my wife lately even though she been a loyal customer of theirs for many years. My wife called Vodacom on the 29th June to cancel her contract with them because it was coming to an end on the 15th of July and instead of them (Vodacom) cancelling the contract as per her request they offered her a new 20+10 gb contract at R179.00 starting from the 1st of July to which my wife agreed. I was with her when this happened. Come the 1st July her new data wasn't loaded and when she called Vodacom she was told it'll be loaded later that day. However, it was never done instead always given an excuse and it has never been done. Today she was told to wait for a call from their team leader by Kgahliso but we know this just an excuse because we have been waiting for the team leader to call ever since this whole debacle started. If Vodacom can do this to one of their loyal customers who has been with them for a number of years then I don't think they are a trusted brand.
