ACP Credit Not Applied

I qualified for ACP, and I was deciding between starting service with Xfinity or AT&T. I ultimately chose Xfinity and I’m seriously regretting it. My ACP credit applied for the first month, come the second month and its has not been applied. I called and they told me that it was because the credit was going to apply the day before the due date, and the day before my direct deposit would process. I couldn’t think of a reason for them to be dishonest with me so I just accepted what they said as true. Today the full bill amount (without my credit deduction) has been deducted from my bank account. What is so frustrating is that I called to avoid this very thing. They fail to realize that this credit was given to us for a reason, because we cant really afford full services otherwise. I’m having such a bad experience with customer service in general that I’m really considering just switching to a different provider to avoid the constant headache.
