Upgrade on contracts - Messed Up

I have 3 contracts with Vodacom, 2 are due for an upgrade. I phoned to cancel my contracts because MTN could give me a better deal. The one contract a deal match was done for me, and the deal was finalized, I specifically asked that the device gets delivered to my office and not at home, as nobody will be at home, but still my home address was given for delivery. The second contract due for an upgrade, I am still waiting for a deal match, as to my surprise, M Mabaso (at the retentions department in Randburg) decided that the device needs to be delivered to me with a contract I never agreed on. As a Red Premium client I really thought I would get better service from Vodacom. When I speak to the call centre, I get sent from pillar to post.
