**** to about upgrade deal

i was contacted on 1 November 2017 by MTN upgrades department by an agent,who advised that i qualify to upgrade my MTN contract. I was under the impression that i would only be eligible as of the 11th of November, however the agent advised i can go ahead with an early upgrade,i asked a few questions about what deals where available and i asked about the bundle deals where you get 2 phones, i was not ready to make a decision on the day and advised the agent to call me the next day, she sent me an email and we i advised her that i would like the Samsung galaxy S8 +Samsung J5 Pro for R679 pm.the agent advised that's fine she will sign me up for that deal. Today 09 November my device was deliverd but only the galaxy S8 was in the box, i contacted the 8080 number and was advised t contact the person i originaly spoke to regarding the upgrade i sent the agent an email and advised that I only recieved the 1 device, and not the 2 as was promised and what was agreed upon when we spoke on 02 November. She than advised that the deal that i want the deal we originally agreed upon was no longer available,and that it was last months deals,never did she make contact with me during the week that i waited for the delivery of the phones that she had made a mistake and that the deal was no longer available i had to make contact and then only i was told about this mistake that she had made,this is completely unacceptable and bad service and this t a client that had been with MTN for well over 10 years,i am so disappointed i want to cancel my contract and port my number to iether Vodacom or Telkom where they have better and more affordable deals,i would like to be contacted ASAP my number is ********** 461
