To right, I'd let people on here know who it is, if he mailed them to the wrong address, then this is clearly not your fault, and at the very least he should reimburse you. I must admit I always ask to be paid f/f, but also I give them the option of adding the 4%, but I also tell them that if there not 100% happy, to return the record and once I've received it, I will give them a full refund no question. I'm sorry to say in your case, you have been really hard done too, I would get in touch with him, ask him for a refund, and tell him if he doesn't reimburse you, then you are quite prepared to name and shame, give him or her a couple of days to respond, and make it known on here, shame on them.
