General DiscussionRating Buddy not accepting my friend invitation.

I got selected for Ratting Buddy beta some weeks ago. I was told to add a bot, but it doesn't accept my invitation. what should i do?

I got this in my profile:

We've received your friend invite and will accept it soon!
...
"rating buddy name here" has received your friend invite and will accept it shortly.

But it was long time ago and until now still no response. Is it just me or anyone has same problem with me?
