FURIOUS!!!*POOR SERVICE*BREACH OF CONTRACT* NO RESPONSE

On Monday 29 Jan '18 I went to visit the Somerset Mall MTN Store for an upgrade. As I entered the store the Manager Allison came to me to assist and I mentioned to her that I’m interested in an upgrade to the LG K10 2017. She then assured me stock is available. Then Georginia the consultant approached me and assisted me. I mentioned to her that I saw a great package deal on MTN's website the same morning on the LG K10 2017 for only R249.00 p/m (includes 200min 200 SMSs 500 mb data). She went on her system to check out the package deal and said to me that the package deal is now going for R199.00 p/m (includes 200min 200 SMSs 500mb data) a further R50.00 discount. I then said to her that I definitely want it and proceeded with the contract, which I signed. She went to the store room to get the LG K10 2017 and on her return, she apologised and mentioned that the phone was not in stock, but will order the phone from other store, which I witness her doing it on her system. She assured me that she will contact me as soon as the phone arrives. On Wednesday, Thursday and Friday I phoned the store, but with no luck. The phone never gets answered at Somerset Mall store. On Friday 02/02/2018 I went into the store late afternoon and a consultant by the name of Lee-Roy assisted me. He then went to the store room and got the phone LG K10 2017 and asked me if Georginia notified me that phone was available for collection. Obviously, my answer was NO. He then went on his system to activate it and to see if everything was correctly loaded as per the contract I have signed for R199.00 p/m, 200min 200sms 500mb data. He then said to me that the contract I have signed for is not for the LG K10 2017, but for the LG K10 2016. I said to him it's impossible! Georginia knew exactly what phone I wanted and she ordered the LG K10 2017. He said to me that he cannot proceed with the activation and will get the Manager Allison or Georginia to contact me the following day. Georginia contacted me on Saturday and admitted that she made a mistake. I said to her that it is totally unacceptable and MTN is in breach of contract, as I have signed for the LG K10 2017, she ordered it and that she knew exactly what she was doing. Why would Georginia sell a phone to me which the stores don't even stock, as she has mentioned to me. On Sunday 04/02/18 I went into the store and consulted with Allison (Manager) and she said to me that Georginia made a mistake and it's not up to her make decisions, but she will be in contact with the Regional Manager on Tuesday 06/02/18, as she will be in meetings the whole of Monday. Allison then contacted me on Tuesday and assured me that the Regional Manager was informed about the matter and a decision will be made on Wednesday, and that a person by the name of Gavin will contact me, as Allison will be attending meetings in Johannesburg. Up to now NO ONE has contacted me! And once again no one is answering the phone at Somerset Mall Store.
