Intermittent ADSL for the past AA+- 2 months

I work from home and over the past 2 months my line has been dropping and as a result I have no adsl connection. Just today it has dropped 5 times! In addition my phone has been cutting out when I talk to my clients.My last fault(I have logged various over the past couple of months) was logged on 18 Sep and it was only allocated to a technician on 22 Sep even though i have repeatedly called to escalate this matter as I urgently need to work. Calls logged as follows:<br> 18/9 - 285CWK180915
