Poor service delivery

I wish to express my dissatisfaction with the service I received from Minenhle on 26 April 2016. I requested that my home telephone number be moved to my new address. I gave her all the details and she confirmed that everything was in order by providing me with a reference number for my service request. She also confirmed that I would be able to retain my old number and that the request would be completed within 10 working days. When I followed-up on 13 May 2016, I was told that my request was not logged and that the service request number did not exist. I had to re-submit my request and I am back to no 0 on my count of days to resolve my service request.
