Blake and Associates - Nightmare Harassment Crew

I had a wireless router ordered them in 2017 which provided me with 5 gigs monthly. Fast tracking to my contract end which ended close to 24 months (2019) I got calls from them asking if I would renew my contract with them, which I then said no of course. Further I submitted a cancellation letter as this was their request, otherwise they would keep billing me. Somewhere mid last year I got calls from Black and Associates saying that Telkom has handed me over to them, which without knowing the billing came up R1589.00. I was left confused however sent them all email evidence I had submitting the cancellation letter prior to my contract that existed at the time. A few weeks went by and I got called again but someone else this time, Like a parrot I had to explain everything to the Black and Associate consultant from the start. Since then, different consultants kept calling me during my work hours to the extend that I got miserable and kept getting ****ed off each time they called. Which to date I get calls from them saying I am black listed and I need to settle my account with them . I get sms's and calls which they dont talk they just hang up each time I call. Guys thanks to you, I cant apply for a ****** house nor for any other credit application......Long story short. Telkom is a bunch of idiotic *****s and can suck their debt collector friends Black and Associates fat toes....I am not paying you fools a cent.
