Paypal recently authorised a chargeback from a buyer for £260, as I am unable to provide proof of postage, even though they gave postive feedback. Paypal say I'm not protected because I can't provide this proof, and I should take it up with the buyer. The buyer did agree to pay me back monthly, but hasn't started paying. I feel its come to the point where I need to take to small claims court. Who do I sue, Paypal or the buyer? And does anyone have any experience of this? Financially I could write it off as a bad experience, but should I?
