Query: Unhappy with Logitech Customer Support

Issue solved! I returned the Harmony for a full refund. All thanks to my experience with your wonderful support team. After screwing up everything on Christmas day (it was a Christmas present)), your support staff said "level 2" would contact me within 24 hours.After waiting 72 hours, I called "support" again yesterday. After waiting 30 minutes, I finally got to speak with a real-live agent who "could not switch me to level 2 without a supervisor's approval." This was after providing the incident number. That took another 15 minutes. I then waited another 30 minutes (total now 1:15) before I had to leave.I tried again several hours later. After being told "level 2 was not available." I hung up and immediately returned my Harmony to ....Thanks, Logitech.-Keith
