GPS Navigation card was ****** while in for repair

Dear clients please be very carefull, my vehicle was in to H j Bosch & son's for accident repair through Santam insurance which Santam told me to use . 3 days later I had to let HJ Bosh & Sons know that the paint was cracking , they booked my car in for a respray the biggest mistake I could of made was forgetting to remove my GPS Navigation card . I asked them about the card and showed me a photo clip that was taken during the repair , I wasn't present when they took the photos and they claim no responsibility. I thought I had left my vehicle in good hands apparently not . More damage than I started off with .
