Cheated out of salary! Jobless and in debt

Hello internet

Ive recently quit my job after my.boss failed to pay me for a few months. Ive been work a contract role and we had an agreement that I would be paid after 3 months as it was a start up...my boss has started to back track on this (written) deal and I have had to quit. While savings have covered a bit, I have fallen into a little bit of debt and could use up to GBP 3000 to cover my rent and a few bills until I find a new job (which I am hoping will be soon). Any help would be appreciated as it will take a while to settle with her and eventually get my money owed as we live in different countries. I am happy to work out a repayment scheme over the next few months.

Thanks in advance
