Not the 4mb line we pay for

We have been with telkom internet for several months now, however we took the 4mb line as advertised for R499, what in reality after all extras amount to closer to R800 a month. <br> <br> Added to this has been a recent concern of very very slow internet, running online speed tests showing results of between 0.4mb to 1.8mb and this has been happening for a period of days already. we have also logged an online fault but still await feedback. we do not even enjoy speeds half that of the price we are paying for???<br> <br> Either they advertise a speed and assume no one is able to verify (provable by going onto our online profile thats STILL says its a 4mb line) or they just dont care about giving the consumer the PRODUCT they are actually paying for... but seen as we are not getting joy out of the fault logging service as per the 10210 number, please telkom consider this our 30day notification that we will be migrating to a service provider that will offer the advertised speed according to the product purchased. Just for interest sake the others offer 10mb for R539 month and 6mb at R359 a month, how is it possible that the company that hosts the physical line cost more than a 3rd PARTY?
