Absolutely no service

Reported my fault on the 1st of March 2016. Reference no. 342CRK010316<br> <br> Today is the 17th of March 2016. Problem has still not been sorted out.<br> <br> I have been tirelessly contacting the call centre and have spoken to numerous call centre agents and supervisors. They tell me that the problem is in hand with the technicians but the technicians are obviously not sorting out the problem. <br> <br> There is nothing I can do from my side other than deal with the call centre which is not able to help me. Someone with the suitable authority needs to take control of this fault and deal with the technicians more effectively and make sure that the problem gets solved. I expect this person to phone me and keep me informed as to what is happening and I expect them to commit to solving my problem within the next 24 hours from now.
