EMPLOYEES who are not trained well

I get a call from my friend telling me i owe these people money.these people have no right to share my business my credit with my friends or family members they are so desperate and will tell your business to the world i obviously changed my number nd they can rather ask people for my contact number thing is they quick to tell ur business out im mean im unemployed nd have no money so instead of contacting me and sharing my business with other people first find out who u talking to people like things and will listen. Im very upset at this
