Customer service at Telkom

Absolutely DISGUSTED in the service of Telkom. I called to follow up on my cancellation and firstly went through to the wrong department and the person in that department gave me so much attitude for being in the wrong department. Told me to call back and push another option. Then I go through to billing to find out my cancellation process and the woman on that side is just as rude to me. So now after two rude calls I get a bit agitated. the woman gets uptight with me and then won't let me speak to her manager. Tells me the manager is busy and I cant speak to them. When I ask for a name, she says, no I can't give you the name. She constantly talks over me when I say I want to talk to a manager. I actually cannot believe someone like that can even get a job as a customer service consultant.
