Sent an item on the Monday and got certificate of posting.  Two days later received positive feedback from customer and gave positive feedback myself.

Four weeks later received message from buyer saying they hadn't received item and were opening a dispute. 

To cut this short, Paypal took the money from my account (even though I produced certificate of posting and explained they had left positive feedback) but no use.

On looking through their feedback saw they had done this before and contacted the seller who explained exactly the same had happened to them. Hope this e-bayer is enjoying her curtains and lamp that she stole from both of us.  BEWARE!!!!
