6 Weeks!

I pay Telkom for a 10Mbps line but I used to get only 4Mbps. They told me that I am further than 1.3 km from an exchange and cannot get 10. I asked to throttle me down to 4 but then I only got 2. So I accepted it.<br> <br> Problem is 6 weeks ago I started getting only 0.5Mbps. I now phone every day and every day I get some story of a technician having worked on the problem or one will work on the problem, thing is no technician has been to my premises in 6 weeks, I received 1 (one) phone call from them in 6 weeks. I am always courteous with the call centre staff since I know it is not their fault - but whose is it? How can I express my displeasure with this monopoly? If I had an alternative I would've taken it but I don't, cell phone data is prohibitively expensive but I am now using that. Wits' end!
