No delivery to an area, and I was not informed !

On 17 January, I ordered flowers for a colleague to be delivered on 19 January, as her Dad had passed away. I made payment and received a receipt. On 22 January I tracked my order, and the status was "non delivery" - I called Net florist and the agent advised, the flowers were not delivered as they do not deliver to that specific area!!! This should have been clear on their booking system!! They are refunding me the cash, BUT MY ISSUE IS WHEN ONE ARRANGES FOR FLOWERS TO BE DELIVERED, THERE SHOULD BE AN OPTION FOR "NON DELIVERY AREA'S" SO WE DO NOT WASTE OUR TIME AND GO THROUGH WITH THE ORDER. Very disappointed with Net florist!!! My colleague will now probably feel like we didn't care enough to even send her flowers. Wake Up Net florist!!
