Phone returned and sent back to me with smashed screen

I purchased a certified pre-owned phone online and it arrived with an issue with the microphone (people I called would say I was breaking up) so I returned it to Koodo using their shipping label and the box it came in. A couple of weeks later I noticed I still had a charge for the phone on my account so I called Koodo who told me it was received but couldn't tell me why the charge wasn't reversed. A day or two later, I received the phone in the mail and the whole screen was smashed! I've gone into the Telus store and spoken to phone reps and so far all they tell me is that because I didn't take a picture of the phone before I sent it back that I have to pay for the cost of the whole phone. Is there anything I can do here? The phone body was in perfect condition when I returned it! I feel like this is a scam! Any advice would be appreciated!
