Begin billed for a non existent account

I cancelled my telkom ADSL account in mid December - and was informed that it would take 30 days for the cancellation to be completed. <br> In the middle of Jan my ADSL account stopped working and I assumed that was the cut off<br> <br> -I am still being billed for 278.84 I dont know about for the month of Feb - march ( and nobody can explain it)<br> -I still have a R700 deposit outstanding at telkom<br> -My account was debited for R568.30<br> <br> My account should be in R1024 credit as far as I know<br> its closer to R600<br> <br> Telkom should pay the outstanding amount back into my account and insure that I have no more debit orders or anything against my name - because as far as I am aware I don't have any business with telkom for the last 2 Monthes<br> <br> <br> <br>
