At wits end

I know this is probably another failed attempt but I am at wit's end and at a point where I will try anything to get some CUSTOMER SERVICE which I pay/paid for!!! It has been over 3months now that I have been begging Telkom to cancel my contract which ended in November 2018 (contract I signed in 2016)and they extended to October 2019(I would like to know who signed this one)!? For the past 3months instead of cancelling they have been sending me welcome e-mails and messages... yes they are welcoming me as a new customer when I am cancelling imagine the frustration!!??? THE WORST PART IS, I HAVE BEEN SENT TO LAWYERS FOR NOT PAYING AN ACCOUNT THAT WAS SUPPOSED TO BE CANCELLED. I A JUDGEMENT ON MY NAME WHICH MEANS I AM NOT ABLE TO GET ANY CREDIT. I must say that Telkom has been the worst experience I have had with any company in my entire life as a consumer in this country!!! If there is any one out there that is able to help me, please give me a number of a Director or GM or even CEO!!! We have been to different malls, sent numerous emails, called way too many time and TO DATE, we have not received a SINGLE response from these guys!
