Billed for cancelled number

I moved homes on the 27th of February, of which i had informed Telkom 2 weeks prior to instruct them to cancel my old number and activate new line as at the 27th February.<br> <br> However when I received my bill for March - April , I noticed that i was been billed for my previous line ( which was supposed to be cancelled) for the period 3rd March till the 4th April. How can i be billed for a line which i obviously have not used since i have moved homes and received a new number.<br> <br> I thereafter logged in a query with the accounts department. I was contacted by a consultant insisting that i must make payment for the total due including the amount that was incorrectly billed to me, and can only expect a credit to my account next month!<br> <br> What company insists payment be made on a service that was never rendered? Why must i pay for services on a line that was supposed to be cancelled on a specific date as i had instructed quite clearly? Surely this situation is in contravention of the Consumer Act!<br> <br> Furthermore, my line has not been working (I cannot make or receive any calls,My internet connection keeps cutting off) for the past week for no apparent reason?I have logged a query for that as well
