Metro Auto Glass

I attempted to get a rock chip repair fixed. The location of the chip on my windshield made the fix a bit of a challenge. I dropped off the vehicle, when i picked up the vehicle, they stated they were unable to heat seal the chip due to it being near my plastic dash. I appreciate their honesty and not harming my dash. However, they claimed to have added filler and thus charged me half price due to not being able to seal and heat treat. That's great, but now what? I could still see fracture lines coming from the chip. They offered to give me a $20 discount on a complete windshield replacement if the crack expanded and warranted a complete replacement. They seem to have meant well, but were not able to properly fix my chip.
