Mtn useless

I received a call from Mtn " head office" on 2 august 2017 to upgrade my contract and was told i will get my phone in 48 hours. On 5 August i went to a mtn direct shop and they told me i upgraded at Summer Mobile in the cape. They could not tell me when or what phone or contract i took. Seeing that it was saturday, i called the number i was goven by mtn ditect on monday 7 august and asked summer mobile to cancel the contract as i wanted to deal with mtn locally. Needless to say we are now at 21 September and that upgrades has not neen cancelled as nobody wants to resolve the issue. Summer mobile blames mtn and Mtn refers me back to summer mobile. For the last 3 weeks Lucia from summer mobile has been sending me mails on my request only that she sent to everyone at mtn and it looks like they are all ***********. Frank Hlaule keeps on saying the Rma has not been updated. I have subsequently approached cell c to get a new contract from them but i need this contract cancelled. Agan it cannot be done as there has been an upgrade done on my name which i never received. Trying to get hold of any Director at Mtn is totally impossible. I will never recommend MTN to anybody and want someone higher than executives to call me. A director in that company like Larry Annetts
