Have buyer whom claimed non delivery, I suspect is dodgy, but I sent second class so nothing I can do.
Gave it the required time and the apologized and issued full refund for item and postage through PayPal.
NOW buyer claims refund has not arrived and says I must refund her again.
What do I do, at what point can I just tell her to sod off? Am feeling deeply irritated (am also pre-menstrual, not helping).
