heavensward

Hi ive been looking for someone to swap heavensward keys with due having a non steam key for it where as my account is linked to steam, i was wondering if anyone has the problem i do or can help me find something to do with this key due to the fact i cant get a refund or sell it on. if anyone's interested or would like to swap or help me find someone to swap, the help would be much appreciated. :confused:

or if anyone could tell if its possible to transfere game time between service account?
