Disgracful service in this day and age

On the 6th of February 2015 I requested both my handset be up upgraded I called the MTN corporate department and spoke to Jessica who assisted by doing the application I was told every thing was done <br> and my phones will be delivered within 5 to 7 working days which never happened. I then called back and ask to speak to Jessica who told me they are have a problem with their system but she has escalated the next day it was a problem which the courier company, she will get back to me that afternoon THAT NEVER HAPPENED. Ever since I have been calling this call centre and always get the ESCALATION word. I then asked to speak to the manager who is Calvin he assured me the matter will be resolved immediately he too had ESCALATED it, he promised to get back to me by close of business on the 14 feb. I requested his email only to fine out this is a totally different company INTER- Active Technologies subcontracted to MTN. on Monday the 16th feb I called and asked to speak to the Manager who is Etienne Nel I was told he is in a meeting will call me by 5pm that day NEVER HAPPEND the next morning I called again I asked for Etienne/Jesicca/Calvin Not available Etienne called but never resolved.
