Xbox Controller Intermittently Disconnecting, Cannot get help from a human

Hi,

Really at a loss of what to do here.

My xbox series X controller has been intermittently disconnecting for the past month or two now. It's gotten to the point where I can't play live games like diabo because my controller will disconnect with no warning. I've tried pretty much everything:

• Power cycle console
  
• reset controller connection
  
• move closer to console
  
• replace controller batteries
  
• factory reset console
  
• connect controller with microUSB
  

I tried going through xbox support and their website refused to let me talk to a live person about the issue: "Live support isn't available for this issue".

The virtual assistant told me I'd have to buy a replacement controller, but I purchased this xbox (and controller) less than a year ago and I have a really hard time believing xbox can't guarantee their products will work for more than a year.

Does anyone know how to fix this issue?

:)
