I need your official fraud department phone number

those are main numbers which are totally useless for fraud or other complex matters

Hi there and welcome to Comcast @user_a5kp60. I am sorry to hear you feel this way. We are here to help you out with your billing concerns. What seems to be the issue with your bill?

@user_a5kp60​ for the first couple of weeks after I transferred my mother's line to my new Xfinity account. They not only cancelled both of our old numbers by never complete the transfer but caused us to lose the numbers to their own network 😂😂😂😆😂 then they had my numbers crossed and my mom had no service for over two weeks. They kept transferring me from agents to agents and from departments to departments . They had me stressed to the max. 

Today, the 18th of May. I've been on the phone with them for 47:37 already because there were two changes on my credit card which are not showing on neither accounts of my(Internet not mobile) and yet they can't tell where the money went to, what account the charges paid. Lawd I'm about have it upto here with Xfinity. 

@user_mshrjw The rep you're working with can get a ticket in place for our backend finance team to investigate the charges and place them to your account properly or refund them. You'll want to ensure you have your banking details available, such as the date of the date and time of the transaction, the transaction ID, amount, etc. for them to fill out the ticket properly. 

Hey @user_nocfup, Thank you for visiting our official Xfinity Forums Community support page. If you did not place an order for any Xfinity Mobile devices and lines, it is recommended to contact our Customer Security Assurance (CSA) team by Clicking Here and select the Identity Theft section. From their, you can initiate a claim process.

If you did place an order and no longer want the devices, our standard return policy would apply. More information can be found by visiting our 'How do I return or exchange my mobile device and accessories?' support page. You can reach out Xfinity Mobile team directly at any time by calling 1 (888) 936-4968.

This gets me nowhere. I’ve called multiple times and I’m stuck in an endless loop of explaining my situation over and over to the same people from the Philippines. There was 2 devices and 2 numbers transferred to my account on 3/17/2026 fraudulently by one of your agents and I was charged $837.86 on may 9th for those numbers and devices after I had ported my actual phone numbers on 4/5/2026. 
how in the heck do I get this resolved?????

If you did not authorize the Xfinity Mobile devices and lines, the next step would be to fill out the Identity Theft form provided with the links above @user_nocfup. In order to add Xfinity Mobile, personal identifiable information would be required. I am positive our CSA team can assist in addressing your issues further. You can also call our main support line at 1-800-XFINITY and request to be transferred to our CSA team on the phone. 

lollll ive spoken to every department every time. without any clue about a billing address nor fon number, they wont help you. they wont back into the account number via the credit card number but nah, that would be too easy, they cant do that. chase can only cancel the card, they cant forever block xfinity. its quite shocking! ive been getting billed for 7 months and cant do anything about it!!!  i appreciate xfinity commenting on this but their system is not designed to do something about this type of fraud where someone tacks on a mobile account onto their apartment complex bulk wifi account. i have 6k apartments, it could be anyone at any complex....
