Appalling service and dead flowers delivered

I ordered an arrangement to be delivered on Friday 1st September in time for a launch. I was told it would arrive between 4-7pm. Nothing was delivered on Friday or Saturday. I phoned on Monday and said this isn’t good enough. Deliver tomorrow (Tuesday) and I don’t want Friday’s delivery which will be half dead by now. The arrangement arrived late on Tuesday 5th and several of the flowers had already died. The chocolates were melted. I will NEVER use NetFlorist again. Just dreadful. .
