Mission Impossible: Closing a Telkom Account

Never have I ever had so much trouble trying to close an account! After months, yes, months! of emailing Telkom requesting them to assist me with closing an account and asking them to phone me as their online cancellation process brings up an error each time I attempt it, and their website does not have contact information that allows me to reach an actual person to speak to, they have STILL not phoned me. They respond to my emails (after a few follow up emails) with instructions on how to close the account, and when I respond to them and inform them that following their instructions is not working, they respond with another email and the same instructions. They refuse to phone me back even after I specifically requested that they phone me. This, in my opinion, is really terrible service! When your Clients have to beg you to phone them in order to properly assist them, and you still don't phone them, are you even a service provider?!
