Cancellation & feedback?

Hi

Sold an item a while ago for pick up. The buyer's communications have been brief & poor, though paid by Paypal. I have twice organised a pick up to be let down  (& greatly inconvenienced) - the first time with no communication, the second time with a  brief "you can keep the bedhead" (?)

I gave the option to cancell the first time but she went ahead a & paid, (or claimed she did, which she didn't untill I contacted her again).

 

Question is - if I initiate a cancellation is feedback possible on either side? I'm a bit nervous due to the communications if she can leave feedback (she put at the end of her details of her being a solicitor)

Thanks
