Bad service

On the 2/10/2015 I cancelled my telephone line *** to which Telkom rep**** via email that they have received the email and would cancel the line. Instead of cancelling the line they keep sending me accounts for October and now November, By the way Telkom I refuse to pay for these months. I have emailed them on numerous occasions with regard to this matter but to no avail. Phoning them is an absolute waste of time as you hold on forever and when you do eventually get through nobody can help. Remember Telkom you are not the only service provider in South Africa
