Urban Planet review: Mistake on an online order/customer service rude and unprofessional!

Went to Urban planet located at Eastgate Mall and they have the worst customer service ever. I never had any issues not until today(December 13). I simply came in as a customer asking an employee for help exchanging the size of an online order they got wrong. I was given a large instead of what was written on the order which was small. You think it would be that easy but no we had to argue first in order for them to help me. When they refused to help me, she even have the guts to accuse me of raising my voice when she's the one being so rude, screaming and telling me that she just can't do anything about it. You're embarrassing yourself with the tone of voice you had. Do I need to beg for you to help? First of all, I wouldn't come here if they hadn't got my order wrong, telling me to send it in mail and get an exchange is not helping me at all. This sweater wouldn't make it in time for Christmas. She told me that online purchases are totally different from in-store purchases and it would be much easier for them if it was an in-store purchase. She was too lazy to figure out how to help so saying "No we can't do it" is the easiest excuse. I kept telling her that I didn't make the mistake on the online order, they got the size wrong. I simply wanted to exchange the size, that's it! Why do I have to go through all of the trouble to send it back in mail and get the right size when I'm already in the store with the receipt and the sweater? Whatever happened to hiring employees that are compassionate with what they do and are willing to help customers without giving them attitude. I got a kid size sweater which was 10 dollars cheaper than what I bought as an exchange.(Thanks to the blonde lady who actually helped me getting the right size.) I didn't get any credit for the difference because I was told they just can't. It's almost Christmas and all we get are grumpy employees like this. If I could give 0 as a review I definitely would. Her quality of customer service is just so bad.
