So about a year ago going to school in my final year of high school i was jamming with a friend and a few of his mutual friends. It didn't go very far and eventually we all found other projects. I moved to another city to start music school and didn't need to have a 4 10 on hand he was using it in his studio, totally fine by me. We stopped jamming and I got my basshead and had to go back to get my cab (I was commuting to the city by public transit) so I had to arrange to get a ride. Our schedules conflicted and we still had yet to sort out a time to get the cab. Its now 7 months later and after emailing and texting the guy he won't return my friends or I's calls to try and get the cab. I hate to do it but what should I do? Should I just contact the police? Is their any laws he may have against me for leaving it there for a bit of time? Have any of you been through this before? I want to do everything thats right and civil. But right now it just seems incredibly weird and im scared that he may have broken,sold or damaged it and is just relucatant to tell me...but seriously? its almost been a year of no replies.
