Super frustrated with doorbell camera - QR Code

For my sanity, please help! As a single mom, I was pumped that I installed the doorbell camera on my own, but it's been nothing but struggles since. 

No matter what I do, my camera will NOT read the QR code. I have tried everything - changing my distance, changing the screen brightness, trying at different times throughout the day (for lighting purposes), taking a picture of the QR code and enlarging it, resetting the doorbell, etc. I have called customer support 4 times and EVERY time I get someone that "can't hear me." How is that possible? I make other calls all the time with no issues. 

I tried messaging support and that was a joke too - "try a reset" - Ummm, I have multiple times!

I had no problem setting up the indoor camera but this doorbell camera has been maddening and makes me want to uninstall everything I bought and send it back. 

Any tips would be appreciated,
