Winn-Dixie review: Gift card customer service

I received a gift card for 50.00 as a refund from my current landlord. I have the card and receipt. When I went to use it at the winn dixie store #1411 in metairie la it would not work. The cashier was nice but I ended up using my debit card as the line was long and busy. Customer service had a long waiting line. I left. I returned today with same card receipts went directly to customer service and
Was told go to cashier! I said it doesn't work! Same response. I got some items in store and the card once again didn't work! The cashier was nice and called the same cs person over who had me carry my bags to the cs desk! She then got on phone for 15 minutes without saying a word talking to no one! She got another person to scan the card and she said it only had 17.00 remaining! I said no! I never used it! Look at the receipts! They would not! She left and other person said so your paying with debit card! I said no! And I left groceries at counter! I was angry and treated like I was causing trouble and they could care less! They did nothing to fix the situation! I called service customer and the store numerous times today with no help and put on hold so long I hung up! I tried to contact thru wd website and it just happens not to be working? Yeah right! I have the card and receipts but I refuse to go back or shop at wd again. I will continue to try and contact them but it seems they know they have complaints and will not accept them!
