Fibre Has not been Installed

I am still waiting for a reply on this issue: Reference number is: SM215413. A representative was sent out to my house to install the fibre but there was a problem with the pipe to the house. It is a simple fix but the technician did not fix it. Instead I was told someone will be sent in two weeks time to fix the problem.. This is unacceptable as it will take another 2 weeks on top of that to get someone to install the fibre. Please can you escalate this as I was initially told 7-10 days and it has now been 6 weeks. This is service is pathetic. Please. I need the fibre ASAP.
