4 faults logged but still no resolution

<p>Since the beginning of the month my 10mb adsl line has not been functioning as it should.</p> <p>I have logged 4 faults each time a technician has arrived at my house, performed some work and told me the issue has been resolved and each time thereafter the connection speed degrades to +- 1mb per second on a speed test.</p> <p>Before this issue started i would get 9.5 mbps download consistently on a speed test.</p> <p> </p> <p>Surely someone competent can resolve this as I have not had decent usable internet for the entire month.</p>
