Internet essentials plus

I was approved for ACP and I was told I was eligible for the internet essentials plus plan with double speed and no equipment charges and that it would be only $29 plus tax but minus the ACP I only would pay roughly $4 because of the tax.  I said ok and upgraded my regular 50gig internet essentials to the internet essentials plus plan.  At least I THOUGHT I did.  Then I started getting weird bills from xfinity for internet and equipment rental fees which I’m not supposed to be paying.  One bill was for $40 something which is NOT $4 and another bill was for $30.  What happened to my internet essentials plus plan that I WAS supposed to be on with the ACP?? I never dropped internet essentials nor did I ever say I was dropping internet essentials, I was supposed to be moved to the internet essentials plus plan with the 100 gigs and the no equipment fees.  Please fix my account because I’m seriously considering moving my Services to AT&T since they have their access plan and will honor the ACP accordingly.
