ZERO customer service

My parcel arrived 5 days ago and is constantly being placed in "Held" status awaiting customs clearance. I have used UPS many time in the past and know there process. I have called for 2 days solid and can't get hold of the customs and clearing staff Linus or Shelley via either the switchboard (which puts me in the holding queue for them for up to 30 minutes at a time) or their direct lines (which just ring until my phone disconnects). All I need is to provide my customs ID and ask that they ship COD...probably a 1 minute phone call!

This is shocking service! I ship regularly and will make every effort to NEVER use UPS again if I can help it...
