Caller: Time-wasting buttwipe

Another stinky butthole calls the office number. I introduce myself. No sound. They hang up.
Why waste my time?
Piss off, maggot.

Caller: Same old butthole

This sh*tfaced turdlicking c***bag called again late in the working day, only to hang up again.
Why? Why waste my time, and everybody else's?
I hope your call centre burns down, and your bunghole gets fused shut!

Caller: This fart-face, again

Smelly nutsack called office again. I introduce myself, and they hang up.
Must be nice having a job where you get to make phone calls, then hang up, effectively doing nothing.
No idea where the call centre is located, but I really hope it burns down.
