Safelite AutoGlass

After only 5 weeks and the mildest winter in the Pocono Mountains ever my windshield is litered with what looks like small cracks.
I bought this car in May of 2019, drove over 30K since that date and had nothing like that in my windshield when it had to be replaced because a rock hit my van. I paid for this out of pocket on recommendation from a co-worker.
In addition to the cracks the car is very noisy inside, no wind is coming in but it much louder than my previous windshield allowed for. Some of the cracks are very high and they are fairly uniform across the windshield .
I scheduled a warranty repair, went to the shop, they told me while they heard the noise on the test drive, the cracks were a result of rocks on the road? ? I completely disagreed, I called again and spoke to someone at safelite regarding the windshield, she stated that she heard of defects like this and re-scheduled my warranty repair, she said she would speak to Dave the manager at the shop who first said my windshield was not defective? so today it was supposed to be replaced and they said Dave said no? Why is this possible? This is a bad piece of glass, it happens? Do we wait for it to get so many cracks that it shatters on me and my children while we are driving?
