Useless as always! I had enough!

I logged a call on the 17 Nov 2017 for a dead land line. Call was closed without the line being restored. Logged another call on the 26 Nov *** - My line was fixed on the 25th Jan 2018. Longer than 2 months without a phone. I phoned 3 times to ask for a credit and on all the calls they just say it must be investigated and then I will be refunded. I want my refund for at least 2 full months. If you can't give me a refund for two months (Plus the interest you are charging me on that rental) be so kind to send me the paperwork to close my account!!! Telkom is useless and refuse to take responsibility for the fact that they provide absolutely no service....
