Very bad service from Blake and associates

I've never experience such bad service in my inter life.

I once had an account with Russells which I've managed to settle on the 25th of July 2019 then I requested for a paid up letter. I was then told my account has been handed over to Blake and associates then I called them and requested a paid up letter until today I haven't received one. Because when I call them they refer me to Russells head office, then at Russells head office they refer me to Blake so I'm sick and tired playing Micky mouse so can you kindly assist me with a paid up letter.
