ADSL Speed test

I've been paying for a 4mb adsl line and Telkom was supplying me with a 2mb adsl line. Only recently has Telkom IT specialist enabled it to a 4mb line...and that took forever... I requested a pro-rata to be worked out which is a fair request ...(I'm paying for X but received a lower product so I need to be compensated ). The calls I've logged wrt the pro-rata are marked as closed....I did not receive any feedback. <br> <br> The Accounts department are not IT staff and keep saying that I am on a 4 mb line. Duh... I have logged numerous calls...The pro-rata must be worked out from when I took out the 4mb ADSL line deal up until it was was actually \enabled"by the IT specialist to a 4mb line.<br> <br> I'm want answers and I want my money that's owed to me.<br> <br> """
