Netflorist stole our money!

We ordered a gift for my father in law on 17 March , order number ***, to be delivered on 20 March for his 71st birthday. Its now the 13th of April and we have had no delivery, and no feedback from Netflorist regarding our purchase. At this point this is theft! We paid for a product and service that hasnt been delivered! This is against my rights as a consumer and someone from netflorist needs to get back to us urgently!
