Added on lines when I requested for an Upgrade

I called Cell C on the 27/08/2015 to do an upgrade and I had been notified within a few seconds by a Sales Agent Aaritha that I can go ahead with my upgrade so I had advised has to which contract I wanted to upgrade to and I asked if I can get that contract on a Top Up and the agent had agreed so I went ahead and asked her to send me the phones has it was a double deal with a cellphone and a tab 7. I called in on the 07/09/2015 to do a sim swap only to find out that I did not have an upgrade done instead I have 2 add on lines. So now I am sitting with 3 contract lines instead of 1 contract. I have spoken to numerous call center agents whom were unable to help me and they just kept transferring my call to another agent were I had to keep giving all my details and explaining my compliant from the beginning to each an every agent. All I wanted was for the call to be listened to because I had requested for an upgrade with a top up contract and not 2 add on lines. Aaritha had called be back but with no information all she said that she can do is listen to the call and call me back and I am still waiting for her or her supervisor to call me. This is by far the worst service I received.
