Unacceptable business practice /ethics

I placed a grocery order on 16th of July. I was expecting my delivery today (6 /08/2021) between pm and 5pm. Just after 2pm, I received an email saying that my order was delayed by 3 hours. It's now 10:36 pm and still no delivery. Am I supposed to sit at home indefinitely until my groceries get delivered? I am very disappointed with the poor service. Last month my order was canceled on the day of expected delivery. Totally unacceptable business practice.
