Alexa needs hearing aids.

I'm getting so tired of repeating myself, it seems that Alexa is going deaf in my house.. I give a command for room lights and she doesn't respond, I ask a question and nothing. She's also dumb as a box of potatoes.. "Alexa, how many inches of rain are we expecting?" her response" Expect rain in 20 minutes, it will rain for 20 minutes." , Me "No how much rain will we get?" A "Expect rain in 20 minutes, it will rain for 20 minutes"... Can we get some "I" in our AI please?
