Please Explain.

We recently listed and sold a pair of Fireking Coffee Mugs.  I added postage and sent the invoice to the buyer, next morning I looked at the sold items list and to my amazement I had neutral feedback for the mugs - at this time they hadn't been paid for so they were still sitting in my rack.  The feedback stated that they were supposed to be FREE Postage - I had a look at the listing and it clearly stated Postage - Freight.


I contacted the buyer and asked for a copy of the listing it was supplied and showed that as she had stated FREE Postage - how can that be.


The sale has now been cancelled and I have asked that they remove the feedback, will have to wait and see if they oblige or not.


Has anyone else had this happen.  At present we are struggling with low ratings and ebay are not very impressed with us, we don't need or want any more problems.
