Complaint Review: Tickets Plus ticketsplus.com

Tickets Plus.com ripped me off by selling me bogus tickets to the Lion King's performance at Proctor's Theatre for March 5th.  I bought five tickets for $100.00 each and they mailed me electronic tickets back in November.  I overheard a woman talking about a problem with electronic tickets so I inquired about it.  She said the theatre double booked seats.  When I called the theatre another woman had my seats legitimately. Feeling mad and foolish!  Can anyone do anything about this?
