Dollar General complaint: Gift Card

My sister bought a gift card on 12242021. She actually bought two. One was given to her son, and one was given to me. Both gift cards were for $100 each. She paid the cost of $4.95 for each of them and put $100 on each of the cards. One card was activated and the other one was not. Upon my sister trying to fix this problem with this store she met up with the manager who refused to give her name. She is a BF around 40 approximately 5’7 tall. Medium build. This is my time dealing with her on 1252022 with my sister. My sister had made many contacts with this so-called manager to fix this problem in which the manager said it was my sister’s bank’s fault. So, my sister checked and called her bank, when there was no reason for her to go through any of this. (this should have been taken care of in store). The bank said the money was taken out from your store at that location. According to my sister, this manager kept on putting off all responsibility on her. Without doing any investigation of her own. Other than calling the 800 number on the back, which we already have done stating the card has not been activated. This means that is the whole problem to begin with. This manager was very rude and unprofessional. I thought I only saw things like this on Facebook. I was beyond myself. No bad language was said in either direction, but it was a very heated discussion. Any time I tried to say something she shut me up. Then I would ask her to quit cutting me off. She only replied that I was cutting her off, which I was not. She was very ugly, verbally, to us. Then another employee chimed in yelling at me to get out. A WM approx. 5’4 140lbs. He did not help the situation at all. He kept putting fuel on the fire. Causing the manager to get more engorged in anger. Another employee, bless her heart, didn’t know what to do. She was threatening to call the police. Which was unnecessary on either side. But back to the fact that my sister is out $104.95.
