Myflowerapp — Order not delivered no refund processed

I had placed an order on 14 Feb and the order was to deliver on same day but the order was not delivered. So i contacted them through email since they didn't had any other contact source. So they said they will deliver on 15 th Feb but i asked for refund so they said refund can only be done on there site wallet but i said i want in source account but they denied so i asked them to deliver the order but the order was not delivered nor they are replying to any of my emails. My tracking number is[protected] amount 1498/-. Please kindly help me with refund. It's a hard earned money
