SC Product Options

They made changes to my theme and pushed them live without testing. The changes broke my theme so now customers can't add products to their cart from the collection pages and can't get to the checkout page. AN issue like that on a live site would have created a DISASTER. I emailed them an hour ago and still no response (during support hours). HOW CAN THEY BE SO IRRESPONSIBLE of making changes to a theme and not testing before pushing live.
Here is a clear view to the rror so they don't claim it wasn't them: http://wethe.me/371a2f5c3d39
