Need to have replacement modem sent out

Hi, lightning struck my house or near my house and there was a surge that fried the television and xfinity modem connected to the surge protector. The modem now receives no power regardless of where it’s plugged in and is no longer usable. 

Can you please help me setup a delivery of a new modem to replace this fried one and let me know where I need to send in this fried one?
