Great job, Rose!

Hello, I am a customer who bought a pair of sneakers last weekend from your online mall, and they were delivered yesterday.
I put them on, but they were too big, and the color was not what I ordered.
Can I speak to someone in customer service?
What you’ve just heard is about your product I ordered.
I surely ordered a pair of black sneakers in my usual size, but another product was delivered.
I don't know why this happens.
I have to wear sneakers this weekend for a marathon.
Once in a while, this situation occurs, but this time it's too late to exchange them for another product, so I should refund them.
Can you help me?
If you would like to have time, please call back to me as soon as possible, thanks.
