Why does your driver who was VERY late, attempt to deliver after your specified hours and expect me to be twiddling my thumbs waiting

Why does your driver who was VERY late, attempt to deliver after your specified hours and expect me to be twiddling my thumbs waiting. Your service is pathetic, your driver only arrives late in the afternoon EVERY time and yesterday wanted to deliver after 5pm. Do you understand I pay you, if all customers stopped using your services your business would fold and you would have no salary. You and your drivers are not doing me a favour, I am doing you a favour having you deliver to me. You are not the only delivery company around. You truly seem oblivious to this fact.
