I have a question. A friend of mine (well ex friend now) has been doing my accounts for a number of years as a "favour", I offered to pay on several occasions and did work as a favour in return. We had some personal issues and I now received an invoice for a huge amount. They had done work but there was never an agreement to pay that amount. The work was also not complete and was only done after I had sent many emails requesting if it was done. I have now been told that I have to pay the amount or else it will be handed over for collection and default listing. I was so shocked to receive an invoice I had to ask what it was for. Since then I have ignored all correspondence.
Please can you tell me what my rights are in this position.
