PATHETIC SERVICE YET AGAIN FROM MTN

I visited MTN Sasolburg on 4 May 2015 to upgrade my cellphone contract.The sales consultant promised to upgrade my phones (3 contracts and one internet stick) = I received a call from another branch a week later stating that I did not upgrade, I contacted MTN again and the same consultant said they were lying and on the system I was upgraded (11 May 2015), on 16 May 2015 I personally visited MTN, the consultant was on leave, the Manager of MTN Sasolburg then confirmed that my contracts was NEVER UPGRADED. This after the confirmation from the consultant. I then again upgraded (16 May 2015) - I then received a call that my phones (Windows Lumia 535 was discontinued - I must choose a new phone - Julia send me the new Yello Trader Book of MTN and I decided on three new phones Sony Experia E4 - today is the 2nd of June 2015 and up to date I still did not upgrade - Julia told me that I have to choose yet another set of phones because MTN erroneously put the Sony Exerpia E4 into the booklet !! And now with the MTN strike they have a problem and I have to wait another month or more! This is unacceptable that with all the lying from the branch and now I have to wait another month or more!
