What are the worst courier companies

For me Parcel Force and Business Post are the pits.

Been waiting for some bits, which should have been here on Monday by Business Post, which maybe not be here until the end of the week now. The pickup guy took all his parcels home so he didn’t have to go back to work at the end of the day (they told me he is getting the sack for it). Their tracking system has all the wrong information, just a really poor service. How can they run a company like this!!

A wasted day at home, rant over!!!!

What experiences have others had?
