Battling for 3 months to sort my account out

This is the 3rd month I am logging a complaint and to date Vodacom has not sorted out my problem. I asked in January to deactivate a Mymeg on my account as I do not require the service, somehow I get told every time that it has been deactivated yet they continue to load the data to my account and charge me for it! You can NEVER get hold of a manager as they are always seemingly busy and will call you back which they also NEVER do! I have been holding for over 20 minutes today to speak with a manager and guess what that never happened!!!! I am actually opening a case of ***** against Vodacom this afternoon if my problem is not resolved as they are blatantly steeling from me now.
