Rude Driver, Shocking Customer "Service"

The courier phoned to say he was arriving in 10mins, I figured I had enough time to go to the bathroom but he arrived within 4 minutes so I got my domestic to tell him I was coming shortly. Within 2mins I was outside opening the gate but the driver sped off and phone calls and sms's were not going through to him. I managed to get hold of him eventually almost 1hr later and he was extremely rude over the phone and refused to come back despite it being critically urgent for me to receive the parcel today. I have now spent the last 3hrs on the phone to their poorly named Customer "Service" department with my call being escalated multiple times and being put on hold with the call being dropped after 15-30mins 5 times. This company is the worst courier company I have ever dealt with, how are they still in business?
