Mr. Sam Menswear Brand - hours and store locations

My parents purchased a $100 gift card from Mr. Sam's in November of last year and gave it to me as a Christmas present. I was just in his store trying to redeem the card, which had no expiration date on it. When I said I had a gift card, he looked at me like I was from a different planet. I showed him the card my parent's purchased, and he asked where I got it from. I replied that my parents bought it for me. He asked if it was stolen, which was an offensive question, first of all. I responded no, my parents had purchased the card from his establishment last year. He indicated that the card wasn't from his place, and asked me again how I got it. Once again, I told him my parents had gotten it for me. He muttered something about 2015, even though the date of purchase was right on the card, 11-21-19, and said it wasn't good. That's $100 that just went to waste because he refused to accept the gift card, not because it was expired, but because he didn't believe that it was from his place. My parents aren't going to be happy when I tell them about this poor experience and how he essentially stole $100 from them. I won't be shopping for dress clothes at Mr. Sam's ever again.
