Got this call 6:20pm 20 Apr. 2016, a recording stating that this is a final notice for a credit card issue unresolved and asked to press one for details which I rejected and hangup. I am sure I have never had any credit card issue at all!

Didn't pick up but the phone rang and rang - bypassing even the tel co.'s voice mail prompt (usually goes to voice mail after 2-3 rings) and then the last ring went on FOREVER - like 20+ seconds. It is maddening that the telcos (Bell, Rogers, et al) have the technology to stop these nuisance calls (99% are made over VOIP and can be stopped by spam filters, just like spam email) but they won't deploy the technology. If you don't recognize the # on your call display, DO NOT PICK UP.

If a number that is unknown to you is a legitimate caller with a legitimate message - then you can always listen afterward and return the call if you wish. If you pick up to an unknown # and it is a scammer, they will then know that your # is valid (information they can sell as part of a list to other scammers), and they will also know when you are likely to be home (also information they can sell as part of a list to other scammers!)

Calls us randomly every week or so... sometimes the "message" left is static... sometimes it's seemingly random radio sounds? (sounds like an announcer on AM radio or some music). Not sure if their autodialer doesn't work or if it's some teenie weenie with too much time on their hands.
