Ever had a really bad day where you've stood to lose a customer because of a manufacturer's poor service?

Thanks to the power of the internet, it is now possible for me to proclaim to others that Honeywell Video's service SUCKS!

Why?

#1 Arguing about fixing products under warranty
#2 Rude people
#3 Sending a repair back to me COD cash or cashier's check without first NOTIFYING ME!
#4 Not returning telephone calls
#5 Hi rate of breakdown

Anyone else have any experiences to share so that others may wish to think twice about selling their products to valuable customers?

(Sorry, I'm letting off some major steam)
