MTN Sanlam Centre Pinetown unapologetically pathetic

I upgraded my contract with MTN and personally went into the store in Pinetown Sanlam Centre on the 08th September 2017.. The sales agent was Kristell Collins, Samsung and MTN was running a promotion the deal was for a Samsung S8 which comes with a Samsung J5 Pro and a complimentary 2 night stay, I signed the contract on the same day however was unable to take my phones as the store didn't have stock of the J5 they said that we can still sign the contract and will call us when stock arrives.. My husband fetched the phone on the 14th September however the sales lady that attended to us was not in therefore Musa Mijaka had assisted.. When my husband had asked about the complimentary stay they did not have any pamphlets available and Musa had asked another sales lady in the store who showed Musa a screenshot of the pamphlet and said that we would not qualify as the special is over... this really does not make any sense as the contract was signed whilst the promotion was on and it is really not our fault the store didn't have stock of a phone.. nobody gave us any information on how to retrieve this complimentary stay and my husband left the store with an intention to message Kristell who was the original sales lady. She messaged and her message also did not provide any information on how to retrieve this holiday just asking if we sent the sms (how would we have sent this message, if proper information was not supp****) our response to her message was that we did not recieve any information about it and we continued going back and forth with her and every single time she told us she would get back to us.. Today fed up I called the store and spoke to the manager Tanya Van Wyk she told me that Samsung was running the promotion and there is nothing they can do now, they claim to have sms'd us details on how to get the stay but still cannot provide us with proof of this. We have all the messages and none of which gives us this information. When I told her that I will lay a complaint she gladly said no problem. My husband personally went into the store Kristell put her head down and acted as if he was not there and the manager knew exactly who he was and was already ready for a fight.. very unprofessional.. he spoke to all 3 people that we have dealt with and even asked to see the sms sent and they showed him the exact same sms we have... which is definitely not giving information on how to retrieve the holiday.. after an argument he walked out but then walked back in for their names and walked in on a "gossip session" between the manager and 1 of the employees, the lady had to tell her "sssh he's here"... what kind of pathetic service is this really?!? Is it fair that I am paying for the contract every month however MTN has not fulfilled all of their promises.. so quick for me to sign the contract however useless at providing efficient customer services.. I have been with MTN for over 8 years upgrading every 2 years and have never ever experienced such ****ty services ever.. Pathetic!!!!!
