I did a comercial clean for a shop fitter outfit once, sent loads of bills etc. Then I used a dept recovery firm, they charge £5 and 1.5% of what they recoverd. Also they aplied interest to the amount owing me on a daliy basis.
This went to court ballifs the lot, they got the monnies then went for costs and the firm closed down and moved. They found were they had moved to in another town and sent balifs again and got the monney. This took 13 months in total, then 2 weeeks later I had a letter from a company saying they had gone into recevership and they were dealing with the afairs of the compay.
I was lucky I had my monney, but a lot did not.
So dont delay act.
