A Toronto number. Called back the number middle of the night, they answer "Nanos Research". Tried just for kicks to be re-directed to their service in French; a kinda sexy female voice answered "SDS".

Called a few times in the last few days, nothing the other end. Annoying.Vancouver BC

I get calls from this number almost daily. Never a message and calling back gets "Nanos Research" recording when you call back. Very annoying. Fortunately, they almost always call during the day and my service takes the call. Here's a link to their contact info from their website:

They have called 3 days in a row at 8 in the evening no one there. I held on but they just hung up
