Can't even reactivate voicemail succesfully!

So after 7 years with Vodacom... and continous bad service I have finally decided to port my number to a different network provider, one that gladly wants my business. Left the country 2 months ago and called to deactive my voicemail, 2 months later after numerous calls my voicemail box has still not been reactivated.<br> After first having a consultant yell at me after using the call back option on the website, to having a consultant promise to return my call as there systems are offline (never received that call) to now attempting to cancel my contract... only to receive a msg our call centre is currently unavailable. I cannot find the words to describe how unhappy I am about the service in this regard. I informed the consultant last night (who was meant to call me back) that if I did not receive a return call I would cancel my contract. Clearly Vodacom does not need my business so I have decided to offer it to someone who actually does. Now if you could kindly send me a statement to settle my contract in full it would be appreciated as I am not done begging for decent service & helpful call centre agents.
