Recent info about Oscar Brown Tours?

I sent an email to Oscar Brown Tours over a week ago, but they never replied. Last night, I emailed them again and got an automated message in return, saying that their inbox was full. Does anyone have any recent experience with this company? When I do a search on this forum, the most recent post was over a year ago! Is Oscar Brown even in business anymore?? Their website is still active and some of the tours look great, but I am hesitant to book with them if they won't answer their emails :confused:

I just booked Oscar for February. He's still around. His sister Carol replied to my several emails immediately.
