MISLEAD BY VODACOM - UNABLE TO CANCEL MY UNWANTED UPGRADE

So i've been called by Vodacom for a great deal on an upgrade on an existing line. I've been mislead. Then I phoned 082135 to cancel this upgrade. a Mpumi (user ID BY_KHABAN) HELPED ME. Said she will be handling my account from there, said that the other sales agent definetly mislead me, but that she will sort this out. Confirmed that my number was canceled, confirmed pick up of the already delivered device.

Nothing to date.

Then another vodacom sales person phone me regarding my upgrade and tells me but the 'new upgrade' i was mislead on, was not cancelled, and that i have another contract taken out.

WHAT THE F****

AND I DO NOT GET THROUGH TO 082 125 CAUSE I HAVE TO HOLD ALL THE TIME, AND IF I DONT CANCEL THIS (TAKE NOTE, F**UP FROM INCOMPETANT VOCACOM EMPLOYEES SIDE, BUT I HAVE TO TAKE TIME IN MY SCHEDULE TO CANCEL A CONTRACT I NEVER REQUESTED)

Im trying to reach vodacom's management = no avail

How will this get resolved?
