Hi Gamanadamas77, thank you for reaching out to the Xfinity Mobile team through the Forum. I apologize for the delayed response, and I am sorry to hear you are having some trouble with your promotional card. I will be happy to help get the card replaced if possible. I will need to review your account for the detail.
Can you please send me a private message with the following information to proceed, and verify your account; your first and last name, the full-service address for your residential account, the last 4 digits of the stored payment method on file, and the mobile number the promo card was sent for? I look forward to hearing from you.
