A pay day loan

For the last past two days I have had messages left on my home phone from some non speaking English person. I was asked to call them as soon as possible before I get arrested and/ or  pay 5000 bond because I did not returned the call and own for pay day loan. I quickly called my boss because to notify him about my conversation and to let him know what that this non speaking stating the I will be going to jail tomorrow. I will be picked up by an investigator at 11:00 a.m.I knew I hadn't did any things and told them they will be sued.
