Family Dollar complaint: Rude unhelpful manager on christmas eve

I have been a weekly customer for over 20 years. I got off work late on christmas eve and had to pick up a few things to complete my holiday dinner for my family. Thankfully I found a Family Dollar that was open it was 8:45pm when I got there. After shopping and making my way to the checkout with my overflowing cart, I was having trouble with my EBT card. The girl scanning my items was new and said she would need assistance from the manager to complete the transaction. After 3 times being declined I completed the sale with a different debit card. I returned to my car and figured out I was using an old EBT card. I went back inside and asked the manager if we could refund the debit card that I used and re-purchase the items on my EBT card. He said that he would have to rescan each item and refund them one at a time. I said absolutly I will go get everything and come back in. Then he said he could not help me that it would take him to long. At this point it was 9:05pm the store was complely empty the store was closing at 10pm. The young female co-worker offered to help and he refused to let her help at all, then told me to contact brenda (the day manager) on her next shift. My total bill was $196.81, I get EBT because I am a single mom and having to use my debit card definatly creates a big problem for me. The only reason I didnt take everything back inside and demand a total refund was because it is christmas eve and nothing else was open. What I would like to have happen is to refund my bank debit card and re-purchase items on my EBT card. Can someone please contact me ASAP to fix this.
