When i was running a property maintenance company some years back TCA approached us to carry out some work on properties, worth quite a lot of money but part of the condition, (before i got the work) was to do some work- for free - on the owners home, worth about £600...........the only picture i can recall was the horror on the office manageress face, Chester Branch, When i came in and told her to "Stick this right up his a**e" and thru the all the paper work over the desk.
He was SHARK then and i am not surprised this has happened
Good luck in getting your money Ian
