3 weeks with a fault and not technician visit!!!

I'm onto my 4th ref number 247CWK170215 and have had a fault on my line since Sun 1st feb. I have followed instructions to use internet, SMS etc but no luck. I have waited on the call center line for hours several times often to just get cut off or to be given a ref number and promised a call by the technician within 2 days but still nothing. I have spoken to a manager Bradley Halters who promised that I would get a technician to my house within 2 days to fix the problem but still nothing! 17 days I have been without a phone line or internet.<br> I would like my phone line repaired, my money back for the time I have had no service and compenstation for having no service.<br> Please don't make me wait any longer!!!
