Shocking service from Credit Department

On the 9th of January 2016 I went to the Tygervalley Centre Customer Care branch to move my phone contract from my mother's name to my own. I had my December payslip and 3 months stamped bank statememts ready. I have been employed for three years on an article contract at a auditing firm and was promoted to manager as from 1 Jan 2016. Obviously I had a new contract as this was a new position within the company. The credit department denied my request for a contract because I was not 3 months employed in my new position!!! Wow. So if someone get a promotion from senior management to CEO you will not be able to get a contract at Cell C. Shocking. Now I have to wait 3 months. Very very bad service. I was not allowed to speak to the credit department myself.
