Myflowerapp — Fraud company - Not delivering item after making payment

Website:

myflowerapp.com

I got a message at the last moment that the delivery of the item (Order ID[protected] cannot be done. and when I asked for a refund I was asked to select another item since they can't refund the amount to my bank account. After I selected the item ( https://www.myflowerapp.com/white-potted-sanservia-plant ) I was told it will be delivered within 3-4 days, it's been 6 days and there is still no update. Even after sending the mail none of them are responding.
