Ruining birthdays with poor customer service delivery

So your cakes are delicious, but you guys fail at customer service. You offer an online delivery service, but fail at allowing customers to plan a celebration because you say the delivery will only come between 8am - 5pm. I’ve been chatting with your service person on WhatsApp go check what time our driver will be arriving so I can arrange my birthday celebration. But all I get is a default response of saying driver will arrive between 8 and 5. How does this count as customer service. So you telling me I ordered 3 days in advance (you have a 24 hr preorder period) and you cannot advise if my order will come in the morning. So basically you have ruined my birthday celebration despite me preplanning the order
