Flight Centre unfair on travelers to cancel

Rating Zero for Flight Centre. We were quotated for Thailand when i went to pay I was told Singapore flights went up but the expiry date is not over i was charged more.. I bought tickets 30 December 2019 to travel to Thailand on the 3rd May 2020 . In January Coronavirus broke out. It changed our mood we cant risk our lives. Singapore airline is cancelling flights left and right and what is the fuss all about. We went back to Flight Centre we were told it is too early we should wait or if we want to cancel or change dates or route, we were told we will be panelised.. We find it is not fare on us as it is not personal issues but it is out of control. Why cant they cancel and refund us because if you book online it is easy to cancel and full refund. Other travel agencies dont have issues they cancel why Flight Centre
