Slow ADSL line with no help from Consultants

For the last 3 weeks it has been a constant back and forth with regards to my internet speed. It has plummeted where I can no longer stream movies this applies the WIFI as well. I have received no help from Telkom they said they will send out a technician however no one has contacted me yet. Only thing I got was a sms with the reference number 596CWK211117. This is not the first time that I have a problem with my internet speed, it seems to be a constant battle, it is not fair that I pay for a 2mp line and only receive a 0.72.
