Poor customer service

Poor pathic customer service .I purchased a blouse for daughter. This morning I had to return it as it did not fit. Since we had bought to separate items and got two packets I had taken the wrong slip. They insisted to bring the correct slip to get the refund. I even asked politely if they have the store copy from yesterday. They did have the copy but refused to check it. I was treated like a *****. My child shops there on a monthly bases and spends a lot of money. No more she banded to shop at this store I will allow her to.
