Downtime,Trouble

Idk what the problem is after all the last updates the app, double txts also receives texts hours laters & the calls breaks up with crazy sounds! And the numbers I txt dont have names to them Nomo! But they in my contacts tho! It says that I have a unread message but, I read it & it still does not go away! Like this app was good till this update, like fix or I will delete
