Disgusting Cancellation Service from MTN

I am completing this review on behalf of my father. He has been passed from pillar to post for the last week and a half regarding wanting to cancel an upgrade. No one can assist us it seems, despite numerous calls and trips to various MTN walk in centers. He completed an upgrade online, however due to DSP not being able to complete the delivery (as he works off site and DSP not being able to deliver the phone to myself) he asked them to cancel the contract and DSP advised they would cancel the delivery however he would need to cancel the upgrade on his side. And thus begins the wild goose chase he has been sent on. First, he was told the call center can't cancel, he will need to go into the store. When we get to the store, they tell us that the call center should be able to cancel as they dont have access to the system, however the consultant said she will try and assist us to log a query and she will call us back as soon as she receives feedback. To date, nothing as yet. We try the call center again, and between numerous calls being cut, no one being able to assist, we finally get told that another company was out sourced to handle the upgrade and its not a part of MTN???? Also, lets note that none of this was mentioned when doing the upgrade online?? Further to this, no one can seem to get a hold of this company. It seems as though MTN is quick to take your money and strong arm people into not cancelling upgrades/ contracts due to the rigmarole it takes to have it cancelled. Please can someone contact him ASAP to have this resolved. He has been a client for over 20 Years!
