Family Dollar complaint: Your Cashier stole my 100.00 dollars

Three days ago I was shopping at your store I was purchasing a American Express Prepaid gift card and two packs of cig.s .I told your cashier I was putting 100.00 dollars on the card and I wanted two packs of cig.s .For some reason she rang the gift card up by its self I paid for the gift card and gave her a hundred dollar bill to put on my card she then rang up the cig.s I paid for them .I get home to use my card to pay my car insurance bill and the card dosent work ,I call the number on the card and it says she never activated the card .I have receipt for cig s but not for card. .I go up there ,I shop there at least four days a week she remembers me the other lady working then remembers me the cashier acknowledges I was there I bought the card put a hundred on it and insist she did activate it ,and would not help me because I have no receipt for it but I do the cig s and the other items I bought before the gift card and paid for with my food stamp card .I asked why she rang the gift card up on a separate ticket than my cig.s and she got snappy and rude with me and said because cig.s can not be rang up on the same ticket as the gift card which is a complete lie .I called American Express yesterday I told them what had happen and gave them the number on the card .And they said that the card had not been activated because there was no money ever put on the card .that’s why I have no receipt because she didn’t give me one .your cashier scammed me , you have a thief working for you that is stealing from your customers ,I am calling the Chief of Police for the bossier city Sheriff’s Department tomorrow and IAM also calling the better business bureau .It was a 100.00 not ten not twenty a hundred dollars .
