Poor service and day-light *******

I am extremely disappointed at the service that i received this morning from a Telkom Contact Centre. From the time they installed my fixed line ADSL the downloading speed has been extremely slow, I eventually asked for them to upgrade my package from 4mp to 10mp. But before they could conduct the upgrade the lady who was assisting me conducted a speed test and she established that my downloading speed is 1mp, even though I have been paying for 4mp for the past 6 months. She logged a query with the *** and that issue was only resolved after 2 weeks, but I still paid the full instalment at the end of the month. Last week on Thursday my service was suspended because apparently I have an outstanding amount of a Thousand and some change. When i phoned the contact centre this morning I was advised that it is due to the upgrade, but the speed of my ADSL is still slow as I can't even stream series from Showmax. Telkom sales department advised me that i must pay the outstanding amount irrespective of the internet connection being slow, then they will downgrade my package and when i asked if my money will be refunded afterwards? The lady said she can't confirm that, but this can't be resolved if I don't pay that amount. It is sad that i'm getting such treatment from Telkom as I use Telkom both on my mobile and home ADSL and i have always honoured my payments. I will take this further though!!!!
