Planet Fitness review: failure to provide adequate security

I was robbed this morning in the gym, after a 2 hour work out came to get my gym bag with my car keys, money and id, but surprise to me someone broke up to the locker, the lack nor the gym bag were there, reported to the general manager and she said there was nothing they could do as there were signs around the locker room that they were not responsible, they did not offer me to call the police, they denied that the security cameras catch something.
