Bad Service, Attitude, and No Delivery of Service

I signed a cellphone contract with Altech Autopage Menlyn on 30 July 2015 with Josephine and opted keep my no for life. Instead of my contract getting activated my mtn number was disconnected from network. I went to Altech and I was assisted by Martinique who logged a call with head office and gave me ref no (SD No. 913041) and the matter would be resolved within 24 to 48 hours. A week passed and my sim card still not working, went again and same Martinique assisted me and gave a new reference no (SD No. 918398) that she need to now upload the into another system and she would call me but a week passed, no call. Went again to Altech and was assisted by Messiah as when Martinique saw me she practically hide. Messiah tried to assist me and even escalated my issue to Josephine who then called me back to check how she can quickly resolve the matter. Went again to Altech on 17 Nov 2015 and Josephine escalated the matter to Ridwaan (Manager) who do did not even bother to come out for his customer after 4 months of me not using my contract but spoke from the back. Its been 4 months now and my sim card is not working and the only thing working is the bad service from Martinique & Ridwaan
