The appalling service received from Netlflorist!

I need to lay a complaint on the service(non-service) I received yesterday from netflorist. I placed an order yesterday for a birthday cake to be delivered at my office before the end of 12 August 2024, however this never happened, despite the fact that I placed the order well before 12pm yesterday. Someone from Netflorist called me at 4:30pm to ask whether I will be at the office by 5pm and I said yes, he also confirmed that the delivery will be done before 5pm yesterday. I waited at the office until 5:30pm waiting for the delivery, but I had to go because I had other commitments. Its disappointing that I depended on Netflorist but you never delivered!! I paid for my order to be delivered yesterday and that never happened, I ended up having to go buy another cake for my commitments that evening, your service is appalling!
