Failure to respond to queries

S3-GP43W-WMHYM. Why can nobody at Vodacom give me anty feedback. I have 4 numbers on my account and when I specifically ask to upgrade one of those number, they upgrade the one they think you need to upgrade (and change contract) without think of the consequences. Vodacom has *****ed up my upgrade instruction.Subsequently my contract cell number is now a top up and I am losing my patience when being transferred from pillar to post without having the problem resolved. Ask for a manager and you get told that managers don't take calls. I have been waiting since 12 March, after \running out of Airtime\", for somebody to call me back to get this issue resolved. Today after being on the line for 33 minutes, in a fit of anger and frustration I told the consultant (Lebo at retention) to just cancel my number and not to expect any form of cancellation fee from me. I am willing to fight this in court if needs be. Vodacom you have just lost a customer that has been loyal to your brand for the past 20 years. I know the loss of my meaningless contribution to your revenue is of no consequence to you. Thanks for nothing"
