No service

I have no service for over a month, I have called and logged faults and every time I get a reply saying that the fault has been resolved. I have had 2 technicians come over and clearly did not know what to do. they just make excuses and leave then close my ticket number. I do not know who to contact to help me as it does seem like no one is interested. I would like some one to contact me regarding this/ and I would like the 2 technicians to be dealt with, I have their names and contact details. and also my fault numbers which have been resolved when I have NO SERVICE!
