Hello Nightmare, your advice is sound.Castor,DO NO BE INTIMIDATED,I know you don't like the stress,no-one does, that is EXACTLY how these people manage to screw more money from us.
Accept the money he gives you, get a receipt, have a witness to co-sign the receipt, and after you pocketed the money, tell him you are going to file a small claim against him..ON NO ACCOUNT give him your new address.
Kind regards....
