upgrading

on the 11/09/2017 summer mobile contacted me regarding my mtn cell phone contract upgrade they offered me a samsung galaxy s8 plus which i choose in coral blue and they offered me a samsung galaxy tab edge for free as it was an upgrade special so i agreed. when i contacted them a week later 17/09/2017 regarding the the upgrade to see if everything was in place they told me yes that the galaxy s8 plus was on its way, i then questioned what was happened to the free tablet that i agreedon . a certain helpfull gentleman by the name of Luciano told me that they wernt aware of the tablet but only the phone and that he was going to invistigate it and that they would phone me back but no one has. i phoned them this morning on 20/09/2017 to find out what was happening which took them exactly 11min to pick up the phone which then i spoke to a very rude gentleman by the name Vincent and all he could tell me was they would get back to me and that he couldnt help which then i asked to speak to his manager or supervisor because i need answers he just said they not available and i must leave my details. i then phoned again to speak to a manager which took them again over 5 min to answer and the same gentleman Vincent answered he is then telling me there is no supervisor or manager on duty for the day. which he basicaly **** to me earlier on. i then demanded answers from him and again he told me i must leave my details and he put down the phone. After this i phoned mtn directly regarding the contract and they managed to get Luciano talk to me from summer mobile. Luciano then told me if the phone gets delivered without the tablet i must not sign for it and send it back. which i did.

summer mobile are *********** dont deliver what they promise and there customer service doesnt exist. its been a week now since i have upgraded and still have no phone or tablet but i already have to pay my new primiums
