Exchange policy

I purchased items during the “Buy 3, Pay for 2” promotion. Unfortunately, one of the items didn’t fit. When I went to exchange it for the correct size, I was told that the item was considered the “free” one, so they couldn’t assist with the exchange. I explained that I wasn’t asking for money, just a larger size, but I was advised to either give the shoes to someone else or sell them. What attracted me to the promotion was the idea of getting 3 items for the price of 2, and I never imagined I’d end up stuck with shoes that don’t fit and be told by the store to simply give them away! I am extremely disappointed with the service I received.
