I hate to say it but can't fault Kuiu for the first response. You went a really long time without trying it on then used it and expected a full return. You were asking a lot...
Sure he can, it was a known defect and they should have caught it the first go round. SHouldn't matter how long he waited if they knew there were issues with the shirt in the first place. Their customer service is obviously not up to par quite yet.
