I never paid back Pay Day Loans from 2012

Back in 2011-2012… i was horribly addicted to drugs. I applied for “Pay Day Loans” every other day and got accepted for a bunch of $500 dollar loans that i never attempted to pay back.

I cleaned up my act in 2015 & now I’m doing great, with a Credit score close to 700.

My question is….What happened to the money i owe? How come they never attempted to collect??
