They got the wrong number but these are most likely debt collectors who try to collect debt from places like Smile Care and others who claim you owe them money for service rendered. They may have a claim but it is usually due to a mistake at the company they represent and they are trying to get money for a mistake an employee made.
received a call from them and when we put them on speaker phone they hung up with out giving any details of why they called. We tried calling them back and they do not answer or they hang up the phone.
