Xfinity visa debit card welcome gift expired before activation

Hi, Xfinity sent me a $150 visa debit card as a welcome gift when I first joined Xfinity. I forgot to use it and it expired few months ago. I have not even activated it. I called may times and was put on hold for hours and calls just kept disconnecting. Can you please help me? I am hoping that since I did not use the card at all, Xfinity can send me a new one?
