Can playback video on camera but not download

Hi

 I shot some video on a Canon EOS sl1 and have not been able to download the footage on a card reader, macbook pro card slot, or via the Camera usb. i can play it back in camera and can download it via hdmi but that camera does not have “clean” hdmi so the video ends up with timecode on it. 

  I noticed a chip in the corner of the card near where it plugs into the camera on the right side. Not contacts are damaged. 

does anyone have any ideas on how I can retrieve this footage?
