Where are you located?
Just checked about 4 in my area with nothing
So you're going to do a chargeback because the slim fit jeans don't fit like your baggy chinos, even though you knew ahead of time the no return policy? I guess the rules don't apply to ignorant people. Why would RL help you? You bought them from Barneys on clearance.
Lose some weight, list them on ebay, list them on SF, give them to goodwill are all good recourse. Next time ask questions before buying jeans you know nothing about and then trying to weasel your way into getting a refund. Or better yet buy them for full price from RL and then you can return them without trying to take advantage of chargebacks.
