How Can I Get Purchase And Gift Receipts?

Today at the Stamford, CT L & T store, I purchased 2 mens' cashmere sweaters. They had to be rung up three times because of a variety of mistakes. I was told that the "receipts" given to me were for each time the sale had to be repeated because of errors. When I arrived home there were no gift receipts as I had requested nor do I have a receipt for the purchase itself, only what appears to be a receipt and return slip. Would you please look into this. In the end I purchased 2 sweaters. I am not sure, because it was all so confused, how much I have been charged and how, after the fact, I can get gift receipts.
