It just really a small amount of money, so maybe its really not worth the effort. But supposed I do contact Xapo, I should ask them to... reconfirm the transaction? And supposed that i don't contact them, would my tx expired after certain amount of time and the amount are all gone into oblivion or something? Hahahaha
If it is not worth the effort then just wait, either it will get confirmed or network will forget about it in a few days and in which case the funds will be restored back to the original sender's address, that means Xapo will get them back and you can contact them then and tell them to send it again with proper fee this time.
