Touch not waking up from Sleep Mode for Calls and TXT

I havent read through this whole thread, but I am having a porblem somewhat like this. My problem is that my phone sometimes wont download the text. Someone sends me a text and the phone will wake up, but then i never get the text. And its like it knows someone sent me a text and it starts to wake up, but then I dont get the text and it kinda makes me mad because then I miss a bunch of texts...
