Absolutely no service whatsoever

I app**** for a transfer of a contract at the end of October 2017. After struggling for 3 weeks with promises of being phoned back by the Modimolle branch (Emmie) as well as the contact centres I am yet to receive one single phonecall back. A week ago I decided to just cancel the contract upon which the branch assistant told me that she would send me the payment details and cancellation figures. I am yet to receive them. I phoned again today and was told by someone else that the branch cannot do cancellations - so I waited a week for what?? I then phoned the customer centre again ( ********** ) and the phone was put down in my ear. Our company has over 600 contracts with Vodacom, I cannot believe that the service is so poor, I have never seen anything like this in my entire life. Extremely disappointing.
