ADSL Line Speed - AGAIN

I have a 2048kbs line. On the 28th of January the line sync speed suddenly dropped to 1275kbps. I logged a fault and it was said to be resolved but it was not. When contacting the Telkom representative they said that is a fair speed and they doubt it will be fixed. <br> <br> This is the second time this has happened in 3 months. After battling for some time in December to get it fixed, it was, eventually, but it has now a problem again and with the same excuses when contacting the Telkom representative.<br> <br> This is not acceptable as my line has never had speed problems like this, it is almost half the speed it should be. Please can you resolve this ASAP as I do not see the point in paying full price for half the service/speed it should be. <br> <br> <br> <br> My reference is: 63CRK300116 and the original reference for December was 1104CRK050116
