All you can do is email them. Unfortunately all you can do is email them. They do not have a customer service line. I ordered the wrong size sweatshirt for my son and they sent me a new one in the right size and allowed me to keep the old one. I was surprised. Just send them an email and allow a few days for them to get back to you but they will. Hope this helps!

I ordered a 2X shirt and it was not too small at all.

The t-shirts on Redbubble are very small. The 2XL actually fits a "medium" woman's size. I am not large, certainly not 2XL but the 2XL was way too small for me.

There is a form on the website to request an exchange, and a customer service representative contacts you immediately.

They have live chat options under their 'contact us' area... I had absolutely no problem getting ahold of anyone or getting my (wrong color) issue resolved. Sorry you had to toss it...

Couldn't get an exchange, wound up tossing the t shirt, it was not a quality shirt and the print was of poor quality.
