Default [Q] help needed with text notifications pls!

Hello im new to the forum so take it easy on me...lol! I have a lg optimus l9 phone and i love it. my problem is the notifications. On my last lg phone when i got a text i had the option to choose how long or how many times a minute it would notify me of the missed texts or even missed phone calls. does anyone know how i can change this or if even it has this option on the phone and if not what app can i use? I tried a couple of apps already but none are what i needed to keep me notified of missing texts?phone calls.

thanks in advance for any and all info Mike
