They don’t deliver

I have been waiting now 2 days for a package. Taking off 2 days of staying home because they have changed the delivery date. Each day sitting waiting here and then I just receive an email saying contact not available. I have a bell at the gate. No one has phoned me, and I have cameras to prove there were no delivery. This courier service is a bunch of lairs. I have phoned plenty of times to ask about the package where they will phone back and I hear nothing from them. Let’s see how day 3 goes of waiting.
