2 Month's without Vodacome activation!!

I purchased a Samsung Galaxy S6 edge from the Vodacom online store. The phone was delivered with sim cards, however, this sim card took a FEW WEEKS to activate. I requested a number port from MTN to the new contract and a new SIM card was sent to me for activation. I recieved this SIM over a month ago and it still has not been activated and I still have not been migrated over with my MTN number, yet I am STILL paying. This is really unacceptable as call after call the consultant mentioned that they would escalate the matter but with absolutely no feedback and positive result. This process has really left a sour feeling and makes me wonder why I changed over from MTN to the Vodacom contract...Please may this be sorted out as a matter of absolute urgency, regards, Jay Pillay
