Tried to call back.  Delayed ringtone, then just an open line, then disconnect.  Casing the place?

This is strange. They call asking questions about security systems. This number is registered to a residential address and they called on Christmas Eve... there have been a rash of burglaries in our neighborhood. I'm very suspicious

i received this phone from maximam security . i do not know any body . please take nessecary steps to avoid harmsway
