Poor customer service

We bought curtain rods and blinds for our new home about a month ago. However when we went to install the curtain rods, we realized we had purchased the wrong size. Today I went in to exchange the rods for a longer size, however I did Not have my receipt. Because of this, the lady working really refused to help me in any way. She said I would have to keep the original rods and buy the new rods in the correct size as well. I had inquired about spacers I could buy to use with the rods I already bought and she said that would not work (which I know is untrue). As a result, I took my business elsewhere and the lady lost a sale. I had several more blinds to purchase and luckily I found Bouclair carries very similar rods to the one I was going to buy at covers for a fraction of the price. Overall, their products are overpriced, and their attitude towards customers is terrible. I will never shop here again.
