Total failure with iOS-7

I was using the app the old version and was satisfied was sending messages to groups of my clients now when I switch to send a message every contact name appears in duplicate, so if I send a message each client will get it twice. I have read the reviews of the persons who have upgraded they arnt satisfied at all, so I wont. I am going to delete this app and find a new one. Rediculus
