Hello Hopesa87,
I'm glad you found the community, thank you for posting. I pulled up your account to investigate and I do see that you normally did pay on your own, not relying on autopay.
This was until March 18, 2021, the payment option was switched to autopay. Do you recall making this change online? Did you update your credit card information around that time?
That might explain why autopay is enabled now; looking at your case history, there's no support case that corresponds with that date, so it wasn't a customer service rep who made the switch.
I can certainly put you back on invoice billing again which will take away the $5 savings that come with autopay, let me know if you want me to go ahead with the change and I'll do that for you. I'll also waive this month's invoice fee.
