Please Help - Passenger Side Mirror Glass Got Stolen

[Cheungychums]

Hi
My Ford was parked on the street and the passenger side mirror was stolen (only the glass part was missing and there was not one piece of glass found on the ground), leaving the black backing panel with a very tiny piece of plastic damaged and the heating wire unattached.
Could anyone please help me with how to fix it? I only have a limited budget unfortunately.
Many many thanks
