BB Torch :: It Locks Up, Buttons Don't Work?

This is the second torch I've gotten with button problems. I've been a customer of blackberry and Telus for the past ten years.Blackberry, or Telus doesn't seem to give a care about the substandard quality of their product or their customers.I had a Storm and traded it in due to the buttons simply not working. Bought a Torch and six months later the buttons failed. Sent it in for warrantee and Telus blamed me for a problem I didn't even have to avoid the warantee until I complained so much they reoplaced it a few months back. Now this piece of **bleep** is giving me the same heartache.Called for support and they said to send it in for warrantee work. I'm a realtor and can't anmswer my phone half the time. I can't use the back button or the menu buttons. I get charged every time I send the phone back for an evaluation even though it's not my problem and its under warrantee.
