just what i was thinking
I hope the OP doesnt mind me answering this.
The buyer payed for the bag but didnt pay for shipping so the OP (seller) payed for shipping out of the goodness of her heart. She shipped the item un-insured because of this and after 4 months got a phone call from the police saying the buyer filed a report to the interpol and said that she didnt get the bag and that the OP was scamming her.
As long as she could produce a receipt that indicates the bag had been shipped to the country, the case was closed. But she didnt have a receipt because this was 4 months ago.
She called up the postal office and enquired if theres any way that they can prove that there had been a parcel shipped to that country during that week but there was no way.
The police told her that she would have to refnd the money to the buyer so instead she bought the buyer another bag.
