Wrong contract issued

<p>since last year Sep 2016 me & my partner went to Vodacom Westgate mall to upgrade one of our ****** phone contracts, Vodacom made a mistake by upgrading a wrong phone and till now no one is taking responsibility if I go to the branch where the upgrade was done they tell me that it was fixed but when we call the online they say its not being done, always calling the call centre consultants are very rude & noisy and not willing to assist last week my wife asked for an premature cancellation on one of our old contract but the consultant instead of sending us a quote of the early cancellation he put the cancellation through and when we made our monthly payment the payment was wrongfully put under a wrong premature cancellation</p> <p>Can some one take responsibility and fix this mess as we are now being listed</p> <p> </p>
