I keep missing their call when I am at work. At first I thought it might be someone I know because the number it looks like your average cell number from the GTA. They never leave a message though.I called back from my work once(NOT from my cell number) and got elevator music.. No one picked up.I've also been getting notifications of new voicemails on my phone, but no missed call?  There's just silence in the voice message..Has anyone actually picked up when they called?
