Q: Didn't get the 3 months trial after subscribing individual :(

Hey Masteralviss,

If I understand correctly, you were charged for subscription and did not get a trial period. I would recommend you read this article, it may be able to help troubleshoot the issue. 

If you navigate to this screen on the iPhone, does it show a Free Trial end date?

Manage your Apple Music membership on your iPhone, iPad, iPod touch, Mac, or PC - Apple Support
