I contacted The Admin department and shared my sad story ,begged for some assistance, even suggested some penalty in bank charges or similar ,Requested a refund ,Mimi was glad to pick up the ticket and requested my banking detail for Refund , a couple of days later I'm rich yet again ...Thank you for your Honesty ,No penalty to me ....
