Says he works for a law office and there's been a lawsuit against me.

Wanted me to invest in gas and oil and make residual income. Home based business

Person called and asked for my wife by first name. Then asked if we knew HUgo Morales. We don't know anyone by that name. THen said he would make a note of that. This call has been made on several ocassions from different numbers and it is starting to feel strange. I think someone is trying to get or confirm information to steal our identity. What can be doen to have them stop this.

have called call several times a week for the last several weeks, leave no message. and do not speak when we answer the phone. This really has to stop..
