Telkom ADSL slower than cellphone download

I picked up on 31.08 that my ADSL has slowed down to non existence, as I don't use the Internet that much for You Tube videos etc. I logged a call on 01.09 after which Lebo, the supervisor as the original operator was unable to assist me, told me tech will contact me. 02.09 Tech (Anton) first says slow speed (0.4 mbs) is due to distance, but later confirmed the drop in speed only started 15.08, therefore not distance. ***<br> Received sms that fault resolved on 12.09, however fault is still not resolved and a new fault needed to be logged ***.<br> Sandra at accounts will only give credit from 01.09 as that is when I logged the fault even though I did not receive the 2 mbs service which they bill me for. She then tells me the fault has been resolved and forward going I will be billed as normal. She also tells me my speed is 2mbs, even though I tested it last night to be 0.27 mbs ***<br> Please enlighten me how I should pay for a service that worked perfectly and then just stopped working, even though my house, nor my modem moved?<br> Lastly, the problem is still not resolved and I am expected to be satisfied with a line that does not even manage 0.5mbs.
