Theme messes up in mobile mode

My theme works and looks fine in desktop and tablet mode but messes up and looks terrible in mobile mode. For example, I have a shop page and the listings look normal in desktop but when you switch to mobile, all the listing captions get compressed into the entire page so you can't read them or see more than 2. I already contacted bluehost and they said I would have to update my theme. After spending $41 to do so my theme is still having the same issue. What should I do?
