Not honouring advertised deal

I saw an ad this morning (18 May 2015) SAMSUNG S6 EDGE 64GB on Epic 150 Top up. I am an existing cell c customer, and want to upgrade my month to month contract. The price advertised was R150 pm x24. I immediately called in, and since then several consultants have confirmed that there was an error on the adverti*****t, I have a screenshot of the advert, the online advert was changed at around 9am, and Cell C need to honour this deal. A Team leader, Nirvana agreed to send me an email saying that she is awaiting feedback from marketing, and will contact me as soon as she gets more feedback. I still have not received any feedback, after 5 calls. <br> <br> 1st call at 08:08 (Duration 9:10)<br> Call cut off<br> 2nd call at 09:15 (Duration 22:25)<br> Emailed proof, and then call was cut<br> 3rd call at 9:53 (Duration 4:25)<br> Someone answers but no one speaks.<br> 4th call at 9:57 (Duration 7:34)<br> Nirvana, supervisor agrees to send me an email with information. <br> 5th call at 15:06 (5:58)<br> Ask for Nirvana, and the call is cut.<br> <br> I have a full memo of who is spoke to and what they said, It is shocking that I am being sent around in circles, when I have proof of an advertised deal. <br> <br> Regards<br>
