Netflorist is very unprofessional and disorganised

I ordered a red velvet cake on 13 January for delivery on 16 January (today). It was a gift for someone's birthday. One of the Netflorist consultants called me at 10am in the morning, on 16 January (today, day of delivery) asking to change my cake order from a red velvet to Mozart or something different because they had run out of red velvet cake. First of all, why did they allow me to order something that they didn't have? I orderd this 3 days prior. They had 3 whole days to fix this mess. The consultant said the supplier ran out. But still, why are you allowing customers to order things that you don't have??

So anyways I agreed to get the Mozart cake instead and they said the cake would be delivered by 2pm same day, 16 January (today).

Now it is 6.15pm, and nothing has been delivered. People have beeeen waiting to eat this birthday cake. I mean, this is an order that was made 3 days prior, and messed up. Honestly this is very unprofessional.

How is Netflorist going to fix this mess? How am I getting compensated for this?? Cake was out of stock and then failed to deliver the alternative as agreed.

I am never using Netflorist again.
