Vostro 3670 case side panel stuck midway! Doesn't open or close fully anymore

Made the mistake of sliding to close the side panel of my Dell Vostro 3670, and now it is stuck midway cannot be opened fully or closed fully. Please help!!! Any advice? 

Dell design team, this definitely gets a fail in design / engineering - if you are still interested in feedback as I got an email requesting feedback a few months ago.
