Payment Extension Arrangements "broke" Agreement Eligibility Despite Setting Up Right on Time

Hello, I am having issues with the payment extension arrangement system. Normally, I will pay my bills on the 25th, unless I'm offered to pay up to the 2nd of each month. I'll go through the automated chat system instructions to setup said payment arrangement and extension. I'll get a notification and text saying it was setup right FOR the 2nd of each month, and later a notification and text saying the payment was processed on that day. 

Come a month later when I try to setup the extension arrangement again, I'm getting messages saying I'm Ineligible. I reach out to customer service who tells me I broke the arrangement because the system pulled the payment a day early or later than it says it is scheduled to pay on the system. Again inset it up for the 2nd and it's saying on my end it was paid on the 2nd. This is a issue that is NOT on my end and I'm still penalized for it. Customer service will say 9/10 times that it can't be reversed and that I am still not eligible. This even happens when customer service sets up a payment extension arrangement for me because of the faulty payment system. 

I end up having to call a dozen different customer service reps until one of them can understand what's going on and reach the proper department who can reverse the issue and restore my eligibility. I'd really appreciate if someone can look into this and fix the eligibility problem for me. It's not fair to be penalized when I've done everything exactly as it states to pay the arrangement on time, even with customer service intervention. This is not my fault.
