Mothers day order a mess

My order was placed with netflorist on 06 May 2015, it was arranged that the order would be delivered to my mum Saturday 09 May 2015,I logged onto my profile Saturday afternoon at 16:00 to track my order which said it was delivered at 15:22 that afternoon, however upon calling my mum the next day to wish her a happy mothers day and asked if she'd received her gift did I realize that she never received it. I called netflorist at 9:30 the very next day, it is believed that the driver delivering my order **** that it was delivered on Saturday, I was then told that the order was on its way, my mum received her gift just before 17:00 Monday and the call centre agent who took my call could not understand why I was so upset that my order wasn't delivered on time, I am yet to received a call from the manager of netflorist to date
