What a poor courier service company

These are the worst courier services. They are never on time, and every time have some baseless reason why they couldn't deliver. I tried calling them, but they dropped the call when you said you were unhappy. I can't imagine why businesses still use them. My package was supposed to be delivered to me on the 31st, so they arranged it for today, April 4, and now I get a message that they can no longer deliver. When I tried to call them now, they cut the call after I already had to hold for about 8 minutes to be able to speak to a consultant. This is not the first time I have received bad service from them; it happens almost every time businesses use this company.
