Cell c error by agent

One month ago an agent assisted me during a call for an upgrade to my cell c number . I asked for a pinnacle 1 gig to which she said it will cost R299.

In the same call I asked for another of the same contract, Same device, different colour on a pinnacle 1 gig but I have a number I wish to take onto contract, this line also to cost me R299.

At the end of the call the agent told me let's see if we can get you a discount and then she told me I'd pay R550 for the 2 contracts.

When I received the devices I was incorrectly taken onto the wrong package which the agent captured as a a Double deal on pinnacle 2 gig.

This agent of cell c also told me she will call me when I receive the devices to take the second number I have to contract, I am very sure this agent is aware of the error she has done because she has not been in contact despite my countless efforts in contacting the department as well . Whenever I call cell c I am told, I am unable to assist you, I will escalate the matter. It's been weeks now and cell is yet to rectify this error by their agent

I would like cell C to be aware that I am not willing to pay for the double deal as I clearly asked for 2 separate contracts on the pinnacle 1 gig. Time is going, every call I make I am not assisted. Cell C agents are rude , unhelpful and not competent
