Pay for services not delivered

I signed up for a 10mb uncapped packages, Mweb promised me that speed at R899 and said that the speed will gradually increase from 2mb to 10mb. After 6 weeks it is still around 2mb. <br> <br> When I called in and after spending 40 minutes waiting from one department to another, the line manager A. Abraims explained that I should have done my homework and checked what speed I was able to obtain before signing up. I explained that I did ask the technical consultants to check for me, and explained that its bad service to offer clients a speed that's not realistically possible to obtain, because I'm situated so far from the exchange (something like 2.2km from the exchange).<br> <br> I therefore do not feel it is right to charge me a fee of R899 for a 10mb line if i didn't get a service even close to that (around 2.2mb on average) and the line was dropping the whole time due to the amplification on the signal.<br> <br> Please help
