I am self employed but have had a regular job with a national charity for about the last 18 months. When I started, I put my invoice on Monday and was paid the following Friday. All was fine until about 8 months ago. I put my invoice in and wasn't paid Friday. I complained and put in a second invoice both were paid that Friday. This has become more and more frequent over the last 8 months. Computer errors, management not signing off invoice, invoice has gone to wrong department etc etc. I had never gone more than 2 weeks without being paid until now. I have put in 4 invoices now which total over £1000 just in materials and not one has been paid. The last invoice was paid one the 27th July.
Head Office are now refusing to speak to me, I cannot get through to the finance department and I have literally no money left. I have 2 other people to pay which I can't do and nothing to live on. Is there anything I can do legally to get my money?
