why did my monthly charge increase in one month from $121.52 to $146.52?

Hi @user_8e79ec. Thank you for visiting our official Xfinity Forums Community support page. There could be a variety of factors that could result in an increased bill such as one-time charges, promotional campaign end date, and more. Have you had a change to compare your previous service bills to see where the increase is coming from along with any notifications that would have been provided on those bills indicating the increase? You can find steps to view your service bill by visiting our 'View your Xfinity billing statement history' support page.

We can certainly help go over your billing statements and more. Please send a direct message by clicking the chat icon in the upper right corner of the page, clicking on the pen and paper icon, and then entering “Xfinity Support” in the “To” section. Please include your full first/last name and complete service address (Including the city, state, and zip code), and I'll be happy to help.
