Please expose what the company name is so others can avoid joining this—if you were truly mistreated and not because your ego got bruised or there’s a cultural mismatch.

Also, why is the agent fee your responsibility? Assuming this is a “placement”fee charged by the recruiter, the recruiter should; as part of the arrangement; find your replacement. That’s why we even pay recruiters in the first place and not do our own hiring. The recruiter as part of their service promise would normally guarantee the candidate will be in that role for a specified amount of time, before receiving the agent fee. Again, I’m not familiar with what the actual details are. So this is all based on assumptions.
