Useless Service

I have adsl since last year may i paid for a 10meg line after 3 months of use only got up to 2meg at the most and phonecalls Telkom came and said 10meg is to much they change it to 6meg line also my adsl line was up and down never stable, Telkom came out and said they need to replace my line from the house to the box which they did but from last year October that line is hanging from my house onto the ground over my roof and the old one is still hanging loose. Still they bill me for 6meg line which my speed test only show between 1.2 and the most 2.1 meg but mostly 1.2meg per second. I phone Telkom 1000 time to rectify my problem and credit me and still no TELKOM support.I told them i am not paying the account as they need to fix it before I will pay. TELKOM never responded. Now they suspended my line I tried to phone Telkom twice today holding the first time 36min no answer the second time 42min no answer. I took picture of the lines running from my house. And I will put it on all social media. Cause Telkom dont even have the guts to call me back or to rectify my problem they just cut your line and so be it. I need and answer asap you can contact me on ********** 572
