HiI lent a Paramedic work colleague £500 more than 5 years ago with the promise of repayment within a couple of months. She constantly promised to start repaying the debt but as yet has paid nothing. I have nt seen her for a couple of years and to be honest had given up hope of recieving payment. However it has started to eat away at me and I would like my money plus interrest repaid asap. I have only a verbal agreement with her although it is common knowledge amongst some of our other work colleagues that she owes me the money. The only contact details that I have for her now is her works email and since we both work for the same nhs trust I am reluctant to mention any private debt on using works email.All help gratefully appreciated
