Netflorist charges but does not deliver

I ordered flowers from Netflorist on Friday 6 Nov to be delivered Sat 7 Nov. I used a voucher that I received and the balance with ebucks. The purchase remained in my basket after the transaction was completed. When I enquired about it from Netflorist I was informed the transaction was unsuccessful although the voucher has been redeemed and my ebucks account has been debited. Upon further enquiries I am not getting any response from Netflorist.
