ADSL Line And Speed Problems

Once again, on a Sunday(31/01/2016) just after 18:00, my ADSL line goes down and is up again on the Monday(01/02/02016) morning but the line is unusable. The line speed is below 0.86mbps and I have latency of 587ms.<br> Why is this happening ? This is now a recurring problem!!!<br> <br> I have logged a fault online on the Telkom website on the Sunday but this morning, I get an sms telling me that my problem is resolved. I checked my line and IT IS NOT RESOLVED.<br> Why did Telkom close the fault log when this problem is clearly not resolved!!!!<br> <br> I have given my reference number......<br>
