Ongoing ADSL problem

Dear Sir/Madam,<br> <br> I am now quite frustrated with my ADSL connection. The line has had problems since December, and I have logged about four calls for the line until now.<br> <br> This service works erratically, and then not. When it does the speed is not at all up to standard.<br> <br> After logging the call, it takes about a week for you to actually work on the problem, and the line is back to broken the next day. Your service delivery is next to non existent.<br> <br> The line has been working for two days now, which is impressive, but a speed test on the line shows 0.22 Mbps download and 0.13 Mbps upload for my 4Mbps line. I know that ADSL is a best effort service, but that speed is akin to no effort. The speed is not acceptable and is barely usable.<br> <br> The problems though have only started in December, before this I was happy with the speed and availability.<br> <br> Please inform me if this can be fixed at all, or I should be considering other options for my internet needs.
