I've got one thing for sale on eBay and simple delivery has miscalculated the weight & dimensions or something else Royal Mail says £24+ to send SD eBay says £14.

I sold an item yesterday but I don't know if I will be paid because I used special delivery and not their printed label thing. When or if the item gets sold I will never sell on eBay again. Their system is not fit for purpose so goodbye eBay hello Facebook market place.
