Technicians assistance

I'm now on week 3 with limited to no internet service. I have been promised that this would be resolved. This week Tuesday I phoned and the call centre told me that they will escalate the call, as this was with the testing centre to find the fault. The person at the call centre did a reset on the port. But with no luck. Today, Friday 08 Dec 2017, I phoned again and was told the same story about the testing centre. I asked the lady to assist and she said that she would escalate the call. I informed her that it was already done. She then added the comments and promise me that the technician would call back. I'm paying for a service and don't have the use I need. If this is not resolved by end of business day today, Friday 08 December 2017 I would like a refund for the time that I couldn't use my line as agreed upon. My Escalation reference number is ********** .
