I am having a similar problem...sold a kauri tree on 30th May, he paid on 31st May and still not picked up... He says because he has paid I cant renege on the contract. Grrr!!! I emailed him again last Wednesday and he said his friend will pick it up in the next week or two. Havent heard any more from him. Im feeling a bit intimidated by him, hes very staunch and of course has my address.
