Prestige Flowers UK

I bought flowers online from Prestige Flowers for a delivery to a postcode in the UK. The flowers were never delivered. I was asked to enter a mobile number when ordering, yet they failed to phone the recipient when there was no one home. I emailed a complaint only to be told I had entered the wrong address and according to section 4 of their contract, this will be for my loss. I requested more details regarding what in the address was incorrect. The response was another reason for the non delivery. I then queried this and another name responded with a third reason for the non delivery. It was then that I realised a 'bot' may be handling my complaint. I even emailed screenshots showing blow by blow that their online ordering system asks firstly for a postal code and then a drop down menus confirms the unit number etc., so there was no input for me to make an error. Obviously the 'bot' is struggling with all of this, or maybe there really is a person and this person is also struggling to respond appropriately. Either way a valid reason for the non delivery has not been made by Prestige Flowers and my perception is that I may have been ****med. Please be cautious when dealing with this company online. If a UK company cannot deliver it's product to a UK postcode, then something is amiss.
