Cox states that regular rates can apply after promotional periods. Compare the promotional price or discount on the older statement with the recurring charges on the newer one.
Cox bill guide
Why did my Cox bill go up?
Compare your Cox statements to determine whether promotional pricing ended, a recurring charge changed, or a fee, usage item, or adjustment appeared.

What to check
Four places the increase may be hiding.
A different internet tier, service configuration, or recurring charge can change the monthly amount.
Taxes, fees, and other charges can apply depending on the services and location. Compare those sections independently from the base internet charge.
Depending on the plan, usage-related items or account adjustments can affect the amount due. The statement line items show whether the change is recurring or isolated.
Statement comparison
Use the bill before the increase and the bill after it.
Compare the previous and current Cox statements line by line. Separate recurring internet charges from discounts, fees, taxes, usage-related items, and one-time adjustments.

Questions
Cox bill increase FAQ
Can a Cox promotional rate end?
Yes. Cox states that regular rates may apply after promotional periods. If the statement reflects the end of promotional pricing, the bill can rise even when the service itself has not changed.
Can BillDiff distinguish a recurring Cox increase from a one-time charge?
BillDiff compares consecutive supported statements and separates changed line items. A third statement can provide additional evidence when a charge appears only once.
How does BillDiff check a Cox bill increase?
BillDiff compares supported consecutive statements, reconciles the previous and current totals, identifies changed line items, and checks the statement for known dated billing changes.
Does BillDiff save my original bill?
BillDiff processes the original statement for the comparison and does not save the original bill. Optional non-identifying contribution is off by default.
