On December 31st I redeem two gift cards one for $40 and one for $25 and I have not yet been able to use those cards because Amazon said those codes are an incorrect I have reached out about 50 times no one has called me back or no one has text me back on how I go about Redeeming the card so I guess all of my hard work and getting these receipts scanned and in was in vain what else can I do
