Ask HN: Technical problems with Google Voice

I got a new Google Voice number 3 days back. Today a lady called me and complained that she has been getting a lot of calls to her phone from my Google Voice number for last one month. Every time she tries to answers that, the call hangs up.

Apparently there is no way to complain to Google about it. The only feedback page asks what you like and don't like about Google Voice, it's not a complaints page. Is there any Google Voice team member reading this? ;) Please help me.

Edit: added Ask HN to the title
