I was very lucky I think, we completed a job with sixty houses on it in Bangor north Wales last January. Had to wait a long while for payment, had to pass it to Top Service,the credit reference agency in the end. Anyway,finally got paid for most of the work but had an issue with unpaid cis. Around a month or so later another cheque came through our door for an amount a bit more than the difference that they owed us,we duly cashed that cheque and a further few weeks went by. We then had a call from their accounts department asking about the "overpayment" and would we send them the monies back, apparently there's another company in Scotland with the same name as ourselves.Haven't heard a thing since.. Hope the firm in Scotland got their money.:laugh::laugh::laugh:
