Steve Madden review: customer service / exchanges

Hello, my name is Vanessa. Here's my problem, I ordered some men shoes online I had to exchange the shoes for a different size as I go inside the store the two ladies were talking excessively before asking what they can help me with I explained to them I bought these shoes online I wanted to exchange them. The first thing one girl told me in a rude manner was " I need the receipts to make sure you bought them online " I answered I bought the shoes online but I have the order number and anything you need for me to exchange them the girl told me I can go check and see if they have the size I was looking for I checked they didn't have any I asked what can I do ? She told me I can choose another pair I said it was fine I grabbed another pair and was ready to exchange the shoes .I was told the shoes I was taking were less than the ones I was exchanging them for now I will be taking the shoes plus $20 worth of store credit as she printed out the receipt she told me all I needed to was sign . After she told me in a rude manner once again I just refunded you the money to the card you paid with online . I asked her I thought I was exchanging the shoes and even getting store credit back, she simply replied she can't void or do anything about it all I would have to do is call customer service . I asked to speak to the manager and she starts laughing simply says " I am the manager my name is Lesly " I told her that's not what I asked for why would she lie to me and waste my time when all she was going to do is give me a refund . All I wanted was to exchange the shoes I was so disappointed. This is the worst and first experience never have I had a problem . Not only did I just get a refund I had poor customer service and I was humiliated by the manager . I am a daily customer not once have I had such a terrible experience. I will be looking forward to hearing what can be done .
Thank You
