CVS review: Amazon gift cards1

My name is Mary Shea I go to the CVS in O'Fallon Illinois. to buy all my Gift cards. I went in there a couple weeks ago and bought 2 -25 dollar Amazon gift cards for a Birthday. I go in there 2 times a month and buy 50 gift Cards and I always get a receipt. This time I didn't get a receipt she said they were out of Paper. Because I go in there so much and I work almost right next door I trusted her it happens to us at work sometimes. So I gave the gift cards to my Husband for his Birthday and there was nothing on them. We tried a lot of times said nothing on them. I was very sad because that should never has happened. I handed the girl a 50.00 Bill. Can we Please resolve this matter. I would like to get my Money back. Please contact me Thank you very much God Bless
