ACP Benefit Dead End With Cox and ID.Me Please help

In 2022 myself and another family member were approved of the acp $30 a month by the acp's own website. We both are on EBT so getting approval was easy. We called Cox to apply for my household member’s discount code but were told we had to use the cox.com/acp site. We went on cox.com/ac but after finishing the process the site said "Your application has been denied". It was shocking since acp had already given her their approval. I called cox on her behalf and spoke to 9 or 10 agents all of whom were no help. They all said they could do nothing and could not escalate the matter. I was told that the Cox acp approval dept. is one that they had no way to contact. I was told by cox reps to contact ID.me, the acp government office and a local cox store all of which I did. No of them could help. I felt like the cox reps just wanted me off the phone so they told me to contact people they knew could not help. None of them told me about this forum. I found it on my own. I got so frustrated I gave up and my family member used their acp discount with MetroPCS with ease. My own acp benefit has been going to waste for months. That is $30 a month I have been losing. Just thinking about Cox put us through for no reason makes me very upset all over again. My mother has Spectrum where she lives. All she had to do was call Spectrum once and give them her acp approval code. I have no idea why cox makes it so difficult for their customers.
