Waiting already 4 months for Telkom line to be cancelled

My phone line was ****** on the 8th of March. I went twice to the Telkom shop to report only to be told the second time that the line would not be replaced so I cancelled my (NON) service. I received a confirmation email and various sms's but still was billed end May & June only to be informed on Jul the 9th that only the Broadband service was cancelled. Now WHY would I request only for broadband service to be cancelled if I directly stated that we Do not have a line at all??
