I am beyond mad!!!!!

<p>Ever since I got this contract with mtn,all I did was cry for help and MTN didn't bother.Firstly,I got a single sim phone when I wanted a dual and only got response that MTN doesn't have dual 3MONTHS after calling over and over and over,getting "service champion" after service champion.In all this time I was unable to use this phone because I was waiting for an exchange.Once I made peace with this painful fact, I used the phone.Myy joy was short lived however,phone would not allow me to buy data/ use cellphone banking.It says "unfortunately, the process com.android.phone has stopped" and ends transaction. I cannot begin to tell you how difficult this is.I called again, sent tweets even went to MTN Shelley centre to get help but to this day I have had no luck.To make make matters worse, this message now appears when I make calls and cuts my calls short.I am fed up.I am mad as hell and logging countless "recorded" calls with your supposed service champions has not helped.MTN has failed me.</p> <p>I got the phone in May and have not been happy ever since.I have emails,DM's and so many calls to prove this.</p>
