Billing Not for Student Rate and No ACP Credit Applied

I spoke with a rep and set up a student internet account 200 mb for $35 per month. The rep I spoke to was named Marco and he said due to system errors our bill would be listed as $45 and then go down to $35 for the student rate and then $25 with autopay which I also set up with my bank account. We have had 3 bill-all of them-all for $45. There has been no bank autopay discount either. 

After setting up the internet, a few weeks ago I applied for the Affordable Internet Connectivity Program to get it down from 45 and have not received a determination or the credit.

I bought the cheapest $25 student plan over the phone and set up autopay, why is my bill not $25? Why has the ACP not applied yet on top of this?
