Frustrating Handset

Wanted a 5.8GHz cordless. Researched it to death and the AT&T E5965C was a strong finalized based mainly on a generous feature set, good range and audio. About six months after purchasing, the "0" on the handset stopped responding to touch. I went to AT&T's web sit and found the customer service number. Guess what, there is absolutely NO way to talk to a person, none, zip. So, I packaged up the phone and sent to the repair center. About 4 weeks later, I received a refurb replacement. This was a month ago. Now, I'm seeing the same contact issue on the handset with the "4" and the "7." This kind of QA is deplorable. I'm thinking this thing is going to get relegated to some little used room or the bottom of our local land fill. First time, shame on you, second time, shame on me.
