Someone from this telephone number calls me about 4 times a day. They ring my phone twice and then hang up. I caught it on the first ring today and I could here people in the background and also the person breathing on the phone. They then hung up.
I got 4 to 5 calls today when i was not available to take the call (in meetings etc) and they kept calling, it was kind of annoying. I called it back and all of a sudden i got a voicemail with some guy saying "Thanks for calling the Rewards team, We are unavailable, please leave a msg and we will get back to you".
I highly doubt this is a "Rewards" phone line, nothing in life is free especially the time these people are causing me to waste digging into this. i'm willing to make a wager that this is a tele marketer, tele bill collector, tele fraud or most likely a tele idiot.
