Beware of screen protectors!

When the screen protector is on the phone and when I make calls the screen is black. When I take it off it is normal. I sure don't know why this is so, but I do not like what it does to my phone. I have an email into customer service to see why this is happening. It should work if it's recommended for these Jitterbug phones. I have spent all afternoon trying to resolve this and I am feeling very angry toward this whole wasted afternoon.
