TELKOM DOESN'T ANSWER THEIR PHONE

I've been trying since YESTERDAY to get through to Telkom's accounts devision (option 3 on their line), via their 081180 number - to cancel my account with them. Yesterday, I phoned three times, throughout the day - each call being 20 minutes long. Today, I phoned twice, throughout the day - one 20 minute call, and another 25 minute call. AND STILL NO ANSWER. This is WHY I want to cancel my line with Telkom - they are absolutely useless. TO ADD - we haven't had internet for two days now.
