Telkom - Consistently poor customer service

As alway, Telkom has not failed to disappoint me, at least their customer service is consistently poor. Why does one have to write a negative review about a company in order to get the response that should otherwise have been forthcoming. Anyways, I cancelled my Telkom ADSL and standard line service 1st on the 2nd of Feb then again on the 4th of April, and paid my bill on the 25th of April, 21 days after the cancellation and incidently the number of days it should have taken to effect the cancellation. Here we are in June and I have recieved a bill, What gives ???
