I was involved in a moderate crash. Short story, I was rear-ended and got whiplash, so I replaced the carseat. Luckily, my child was not in the car at the time. I found out that carseats can have invisible damage that affects the structural integrity of the seat. That makes sense.

I purchased a new seat from Britax. The box came extremely damaged. I reached out to them because I was concerned about the safety of the seat due to shipping damage. I can't get them to call me back. All they did was email me asking me to send pictures of how the package arrived and to open the box and inspect the seat. They want to know if there's anything looks damaged on the seat and if all the functions work (harness tighetening/lossening, recline, headrest adjuster, etc.) 

I tried sending pictures, but it keeps saying the email ends up being too big, so it keeps failing. I can't get a hold of anyone. I've left numerous voicemails, and no one will call me back! I also don't understand how we could know if the carseat is still safe to use when damage can be invisible. My old carseat physically looks fine, with no visible damage, but I still had to replace it, but this new seat arrives like this, and I'm supposed to trust that it's safe? I can't even talk to the manufacturer because they won't call me back, and I can't get my pictures through, and I need a carseat!!

Does anyone have any experience with this?
