Contact number for missing refund

Hi.  I filed taxes for my brother using TT and he requested a paper check (don’t ask!).  The status indicated it was sent on April 12th, but he never received it.  He filed a claim and received a packet from the IRS which included a copy of the refund check. BUT… the check was made out to someone else (different name, different address, same amount).  He tried calling the IRS number [phone number removed]) but can’t seem to get to a live person even though it seems to indicate that you can.  Is there some sort of trick to get to a person or some other number to call?

Thanks.
