I confirmed a trade with laprasman on November 4th. A week later, he asked to alter or back out of the deal, but we arranged to keep it as we originally agreed. Today, he messages me and tells me he's canceling the deal. I have PMed him back to get more information why, and forewarning him that it's against the rules, both mine and Pokebeach's, to back out after exchanging addresses.
Therefore, I am preparing to leave him a negative ref if he is insistent on canceling. I know the rules say to post here once the ref has actually been left, but since this is the first negative ref I will be leaving, I wanted to follow it through in advance. Just making the situation known.
