How can I downgrade my service online? (NEW)

I want to be downgrading from Ultimate to the lowest internet package my download and upload speeds aren't anywhere close to the 300mbps however that is not the problem the problem is the overage fees it makes no sense for me to on the ultimate package. That is definitely a better choice for me since I refuse to pay this extortion from COX!!

Heck, if the AT&T connection works out, I may drop COX completely because this 1TB cap for all tiers is such BS in my opinion!

I would also like to personally thank the Cox marketing genius who came up with the 1TB cap across the board... BRILLIANT!!
