Made to feel like a ********

I went to MTN store in Gateway to take out a contract for my son on the 15 November 2015. I left all the required documentation and on Monday the 16.11.15 I was notified that my application was approved. We were waiting for my sons old number to port. On Thursday 19th my son received an sms to say the port was successful and then another to say it had been cancelled. On Saturday 21st I went to the store and Gerald said there was a problem with the application and he will get back to me on Monday. I never heard from him. I went back to the store to be told their was suspected ***** and the store was being investigated. after many phone calls I found out that their was suspected ***** on my ID and I needed to get an affidavit to say I have not been involved in ***** with MTN and a certified copy of my ID..I have asked on numerous occasions to speak to a manager or for the regional manager to phone me but to date I have not had a call. surely MTN should call me for a matter this serious. If it was not for the fact that MTN is the only supplier to offer the package I am looking for I would have walked away ages ago. Where is MTN management when you need them????
