MISLEADING SERVICE

I app**** for an additional contract from MTN on Friday the 16/10/2015. I was told by Elizabeth from the cresta branch that I would receive an sms to say if the add on was approved or not. On Saturday the 17/10/2015 at 7.24am I received an sms stating the following: `Congratulations your MTN application has been approved, please wait for a call from a dealer`. I walk into the branch to pick up my phone only to realize that the credit limit was not enough for that phone. So Elizabeth sent the application back to MTN head office so they could increase the limit. Only to find out yesterday that the entire application was declined!!! How misleading is this??? I have been a client of MTN for 10 years now and this is the service I get??? Simple argument is how can you guys approve me and decline me the next day?
