Ferns N Petals — delivery of order not received

I have placed my order on 18 Jan 2018. committed Time was Standard Delivery
18th Jan 18 18: 00-21: 00 Hrs. by them. It is not delivered until now.

Order No. #4472543

they do not contact for anything. when I called them today they denied for refund my amount when I said It was required only at that time still they denied for revert back.then I ask them to deliver so they said 150 rs more wil be charged for redelivery. I denied for that amount then they said I am a valuable customer so they wave off. again they commit that order will be placed by 12 pm to 5 pm but still not delivered.

This is kind of fraud and wrong commitment is waste of time. I want strong action for wrong commitment.
