Very bad experience - Freelancer Gumption Group Employee Review

I started as a freelancer withRank1. there was no transparancy about the day rate. I found out 1,5 years later that the uplift was 27%. However, even this did not seem to be enough to deliver administrative things in time. After almost six years I wanted to "break free". I got no response at all to my proposal. They simply stopped paying the invoices. resulting in 20K+ in damages.
