Who called from 8564813973

called and hung up on answering machine

just calling and nothing , empty sounds.  Think this maybe a stalker or one of those heavy breathers.

Heavy breathing stalkers should inhale enough Carbon Dioxide from a cylinder, and that'll get rid of their breathing problems.

No Message --hangup

Caller ID says Blackwood NJ. I called back and got Thank you for calling MRS. Hung up on their recording and Googled MRS and New Jersey and got that it is a collection agency. Since I have no outstanding past dues, They are probably one of the ones that try to collect bogus debts
