ACP credit not applied

Hi,

I applied for internet essentials in Jan and got accepted.

Then, I got accepted for ACP program. I also connected my ACP info to Xfinity. Successfully got ACP credit in January to cover my bill.

I also increased my Internet speed by upgrading to internet essentials plus (which is still covered by the ACP credit).

In February, I didn't get any ACP credit though.

I also got a bill for $30 for the internet essentials plus. 

So, I called customer service to see what's wrong. They told me it is going to apply but it may take time. 

I called again, they told me I need to call the ACP program guys to see what's wrong. I called them and they told me as far as they are concerned, I am qualified and enrolled and my ACP ISP is Xfinity. And that they didn't stop my ACP for any reason. And they now suggested I call Xfinity!!

So, I called Xfinity for the 3rd time and I was told that the credit will apply before a bill is due. I wasn't comfortable hearing this.

So, I waited and as I expected I was billed and an automatic payment was processed for $30 

I am really upset. I shouldn't have been charged at all.

And I was promised things would be taken care off before the bill is due.

I am also afraid that what happened might disqualify me from ACP which has already stopped taking new applications in case I need to do it again.

I don't know what to do now and I am not sure if this thing is going to be repeated for future bills.
