Behringer Model HDS110 Issue - Is there Customer Service # to speak with someone?

New

I just purchased this set from someone, having issues with one of the toms not working...It was working, now it's not.  Set was working fine.  Maybe I'm doing something wrong.  

Need to get a hold of someone to find out what's going on.

I'm a recreational user, just playing with it for fun.

Thanks!
