With special thanks to all those who contributed.
CASE NOW CLOSED THANK G-D.
Lessons learnt on both sides, I feel, most of them on mine. Complacency leads to items being put up which one assumes are fully functional - must check in future.
Mustn't over react - difficult to bite one's tongue when provoked.
Thus said to call a man a spiv or something close to it is not wise - far more deplomacy could have been used!
Over - finished. Thank you everybody for your advice. Fred.
