If they offered a new, more expensive seat to every unsatisfied customer, they'd be out of business. I'm not surprised they didn't offer to send an insert to someone who has a seat with a DOM of 2013. The OP didn't say what the history of the carseat is, but it's possible it's a loaner from a friend or family member. The fit of the harness on that baby doesn't look that bad to me. I've seen higher buckles on babies. Remember, this is a rear-facing seat, so having a buckle on a belly isn't as big of a deal as it would be for a forward-facing seat. The chest clip is clearly too big, but it is what it is. The solution is a different seat.
