Yes - I managed to get the PayPal reps. name and employee number. I noted the call time/date and content of the response.

Actually the chap I spoke to was pretty helpful and understanding and was surprised at the automated response I had received to the seller's refund offer - given the circumstances. Maybe the reasonable side of me will accept it was a genuine mistake if it is resolved without further trauma!

Interesting I just got a 'satisfaction survey' from eBay regarding their responses. I enjoyed filling it in a lot (not that it will make any difference).
