Did your employment contract not have recruitment costs mentioned to be recovered in the scenario you quit during probation? It would be helpful to get to see your employment contract and also if they had sent any company's terms of policy or something like that on the time of your on-boarding. You can mail them to me at email@example.com, if you want me to give them a read.
