Belfast Kings Hall

Belfast Kings Hall

Hi.
I am looking to sell my 2 P!nk tickets for 16th June for Belfast.
I was given them at Christmas but now i am unable to go over to Belfast for the concert, due to the price of flights.
I live in South west UK and am hoping to sell these and purchase 2 tickets for a UK show instead. I only want to sell them for face value.

Could anybody help me on what my best options would be? or does anybody know anyone?

I really appreciate all the help i can get.
