Discovery+ Subscription Payment Issue

On 2/10/2025 I received an email Xfinity that my Discovery+ Subscription was confirmed. On 2/12 I received an email from Discovery+ that they were unable to process and after reaching out to their help desk they indicated that there were multiple transaction failures. As the payment goes through Xfinity I don't know how to correct that. The Xfinity  Chat is unable to help and the phone kept bringing me back to the chat. I would appreciate if an actual agent could take the time to address this issue.
