Cannot provide reliable ADSL

I have had an ongoing fault for 2 months, and recently it has just got worse. Initially it was only my ADSL and only at night. Now it is both my ADSL and voice service, and during the day as well.<br> <br> I have placed 5 FAULT REQUESTS and have even escalated it (escalation reference 664932), but every time I get told it is fixed, it either is not fixed at all, or the \fix"lasts one or two days (like the most recent \""fix\"").<br> <br> How does a customer get any kind of service from this company"
