Recently order a product that was shipped by UPS signature required on delivery. I missed the first two attemps because I work, I took a day off to be home at the time specific on the UPS form.
After waiting all day at the house (hours were from 10-1530) I had another appointment to be at. Since UPS can not be professional and delivery on time and they specific the product was returned.
The company lost a 500 dollars sale and UPS lost a customer. I'll assume if the company lose enough business they will switch to a company that can get the job done.
Monetary Loss: $500.
