My DSL line speed is not what I am paying for

<p>I am paying for DSL fastest with line speeds up to 10mbps but in the past two weeks I am only gettinng lines speeds up to 6 mbps or lower. I logged a fault with Telkom on the 28th February 2017 Fault No. 301CWK280217 and since then have been contacted by Telkom engineers who say the problem is resolved and I am sent an SMS from Telkom confirming this. However when I test the line speed it is still 5.76-6.00mbps.</p> <p>I constantly explain that two weeks ago I was receiving 10mbps but now only half that speed yet being charged the higher rate for DSL fastest. Nobody seems to be able to deal with the problem and I am going round in circles.</p> <p>I went to a Telkom shop but they could not help with anything and referred me to the Telkom website. That was a disaster as I tried to 'chat' with someone about it and was instantly 'disconnected'. Now I have had to sit waiting on the phone for one hour and have logged a new fault on the existing problem. I have been investigating on the internet and have come across forums where people have been experiencing the same problems and are faced with a 'brick wall' from Telkom. YET Telkom still continue to advertise and charge for something you are not getting! Telkom get your act together and look after your customers otherwise they will move to another provider. When I upgraded to DSL fastest Telkom did a check to see if my area could receive 10mbps and everything was fine so why now is it only half the speed? </p>
