Clarks

Had a problem with a Christmas gift i’m trying to exchange at the Yonkers Ridgehill Clarks. I got the pair of shoes as a gift from my parents with no receipt. I want to exchange them for a better fit but the customer sales associate at the store will not assist me.
Most stores have a policy of return or exchange for Christmas gifts for a certain period of time but I find it very strange Clarks seems to have no gift exchange policy? I have 6 other pairs of Clarks at home and have had a good experience with the store up until this point but the fact that I can’t exchange a gift is deeply disappointing.
I can say that from now on I would not consider buying another pair of Clarks after this bad experience.
