Bad service, poor poor

Good day

I was retrench last year may 2020, I just find a job, I contacted rcs game collections to make payments arrangements, i told them i can pay R500 a month until I get a permanent job they not the only people I have to pay, i was told i must pay R1200, if I don't pay that then they can take my arrangements they will hand me over to lawyers, what kind of people are you that wants to force people, I'm trying to pay but you treat me like my R500 doesn't matter
