POOR TIME KEEPING/ FALSE PROMISES

I placed an order at 12:35pm while i was at work and was told it will be ready in 30 minutes but i waited in vain. Only for them to call me at 14:04pm to tell me my delivery is here, now how in the world was i supposed to get that order when i had already left work. And this is certainly not the first time and im sure it will not be the last. IM SO ANNOYED RIGHT NOW
