they called us tonight and said that they would give us a free alarm system...they also said that they were adt.

We got the same call, they said they were selling ADT alarm systems, and would be in our area.  We called ADT afterwards, and ADT said it was not them, or a branch office.  Not sure who they really were.

Call asking if we had a home security system because we were "selected" for a new system.  Not sure if it was legit or someone trying to get into people's homes.
