underwear

Good day, I bought underwears at Sammy marks Pretoria on Tuesday, so I noticed that one of them has a small hole sort of like a reject underwear. So I wanted to know since you don't exchange underwears because of hygiene but in my case what do I do because it's a damadged underwear it's can't be 're selled anyway because it's not in a good condition. Please tell me what can be the solution. Thanks
