Incorrect products delivered - No acknowledgement

Hi - I placed an order on Tuesday 23 February 2016 for delivery on 24 February 2016 as part of my anniversary gift for my wife (Order number ***). When my wife brought the delivery home I realised that this is not what I had ordered - I have sent 2 emails (One on the Thursday and the other one on Monday), receiving an auto-reply on both emails stating that someone will make contact with me within 9 business hours - to date, I have not heard anything from NetFlorist. Very poor show - at the very least, I should be refunded the difference in price for what I paid for and what was delivered.
