Xfinity Support

Can I have a provisioning engineer check my model upstream signal? I upgraded to the 2Gig Internet yesterday and bought the CM3000. I spent all day dealing with T1 troubleshooting and I am not confident they sent the right configuration file. 

I had a technician come by and confirm that the incorrect configuration file is being provided and they need to push the correct configuration. Previously I was on the old 2Gig so I think Tier 1 is confused.
