Early Termination Fee

Due to moving I needed to close my Xfinity mobile and internet services. Once closed there was a $70.00 Early Termination Fee added to the account. According to the Xfinity website https://www.xfinity.com/search?q=termination+fee it states, "Xfinity Mobile does not require a term contract, allowing customers to cancel their service at any time without incurring an early termination fee."

How do I contact a real customer support person to get this refunded? The customer support person I spoke with said this only applies to mobile but when I log into the account and search for termination fee, there is no designation that this does not apply to internet as well.

Thanks for your help.
