Very bad service

It's almost 2 months that my landline is giving problems. I reported on 5rh April with ref no ********** . As soon as tech went off line was dead once again. Reported several times thereafter and technicians couldn't sort out. Either goes dead completely or noisy line. Last ref no is ********** 3. They are very efficient in sending me a bill though for services i haven't received. Absolutely bad service. The landline no in question is ********** 324. This is very upsetting.
