Telkom - worst service in the country

I have had it with Telkom's pathetic service!! I cancelled my landline last year because of this and then saw an amount of R130.14 being deducted every month. This dates back to 2014 when I took out a mobile account on my landline account. Of course, according to Telkom, I didn't cancel the contract. How convenience, where will I find proof more than 5 years old? I have been trying for more than two months to find someone to cancel the subscription for me as I've been paying for nothing for years. I call 10210 and they refer me to 081180. 10210 says they can't help because they only work with landlines and 081180 (after not being able to tell me how to cancel it online), transferred my call because they also couldn't cancel it. I chose option 5 as told and then that person says they can't cancel it because its linked to the landline. So I call 10210 again and the person hangs up on me while I'm talking. I've also been advised previously to go to the Telkom Store, but.. wait for it... they can't help me! Someone would phone me back... they called me once and I missed the call. No one has called me again. What am I supposed to do? Just pay Telkom for eternity? Pathetic.
