Get all your information together, have all messages / emails printed out etc. If they are calling you get a digital message machine and copy the messages to disk, contact the police with this evidence or seek legal help via a solicitor. A solicitor will charge you a fortune and I know you already have debt so the police route would be cheaper. On the subject of your debt, contact the citizens advice - work out how much you owe and try and consolidate it to reduce your % of interest being paid per month (only putting you further in debt).
You can contact the people who you have debt with - tell them that you can't afford the repayment and ask for a payment plan. Most companies would rather get into a payment plan with you than you simply not paying them at all as this costs them more in the long run to have to contact you, take legal action etc.
