The left collar point is actually 1/2" longer.
The collar is actually not overly thick like on some jackets so once they fix the lob sided issue, it will be fine.
At minimum, MINIMUM, Langlitz should refund you for shipping the product back and forth. Bennie and Scott have always been standup guys to deal with so it would surprise me if they didn't take care of you. Sorry to hear about the issues.
