Comcast overcharged you? Here’s what to do
Summary: Surprise Comcast charges — fees, rate hikes after a promo ends, or services you never added — can be disputed and credited back.
Why Comcast overcharged you
- A promotional rate expired and the bill jumped.
- Charges for services or add-ons you never agreed to.
- Equipment fees after you returned the equipment.
Step by step: what to do
- Pull an itemized bill and compare it to what you signed up for.
- Call Comcast at 1-800-934-6489 and dispute each unexpected charge.
- Ask for a credit and to lock in the rate you were promised.
- If unresolved, file an FCC complaint and dispute charges with your bank.
Common mistakes to avoid
- Not catching the jump when a promo rate ends.
- Paying for returned equipment because you lost the return receipt.
What to say when you call Comcast
- My bill went up unexpectedly — please itemize it and credit back the charges I didn’t authorize.
