Thanks, I have just offered the buyer to send back COD could not be bother with people like this and yes in my advertising I explain to people how to measure and I have just measured all my belly bands I have left, they all measure between 43cm to 46cm. I think I know what is wrong, this buyer purchased and did not pay for nearly 2 weeks, I sent messages to them and then proceeded to open an unpaid item case. Pay back? I am just surmising, anyway the COD option should keep them happy. I'm done.
