Need to cancel EBBP benefit to transfer to another company. How to disenroll from EBB credit towards my Xfinity bill?

I had signed up for the Emergency Broadband Benefit Program and applied the benefit towards my Xfinity bill. Now, I would like to transfer my benefit to another provider.

I've already chatted with one Xfinity representative, who told me to call the government, who said they couldn't do that and told me to call customer service. When I asked an in-store representative, they told me to call Xfinity customer service.

Can a representative please help me to cancel the EBB credit towards my service with Xfinity?
