siwakorn am very much older than you so try and respect me am 56years of age and have been in business for more than 28years now......your inspection fee is nothing to me but you just have to follow our company procedures....its already written on the inspection form that your fee is 100% refundable so when there are written agreement like that and its been signed by both parties there is every binding between us that we have to fulfil and if by anyway we fail to fulfil as promised you have every right to sue us
