Very bad service

I app**** for a R139 mtn contract( using my own phone) on 23 March 2016. I received a sms from mtn on 24 March 2016 that my application is being reviewed. Today, 29 March 2016 I'm still waiting for my contract. I've submitted all the necessary documents to mtn via the Heidelberg, Gauteng branch. All should be in your possession<br> I've retired and own 10 flats (bond free) with a nett income of more than R20000 pm. I also have investments of more than R200000 at a local bank. That staff at the Heidelberg branch were very friendly, efficient and helpful. My problem is with MTN head office for taking so long with the possessing my application. Really, R139 contact using my own phone. What's the big risk?<br>
