Stay as far away for Vodacom as possible

On the 18/12/2017 after visiting a Vodacom shop I was informed that I can only close an account on the phone and they gave me the number to phone. I phoned and cancelled my contract -received the following reference number 1/ ********** ********** . in Feb upon receiving another account I phoned again, on the 18/4/2018 mailed and phoned and today I get an text to tell me I have been blacklisted. after phoning the number again today, if I give my MTN number they just disconnect the call. The say the least- this is the worst place to have a contract, and i will never ever have a good word to say about Vodacom!!!!! Customers never come first here- we are treated as *********!!! Terrible company and no phone manners either.
