If you can hear the motor trying to open it, but it won't, then it's the cable. A new cable is pretty cheap. It's a little bit of a pain to DIY, but definitely doable. Just takes an hour or so.
Also, there's an emergency release in the trunk, behind the panel. You should be using that to release the lid. Sounds like you're pulling on the lid trying to get it to open. Good chance of breaking it that way. Try the emergency cable until you can get the actual lid release cable replaced.
