I got several calls from this number in recent 3 days too. No message left.

multiple calls, no msg

They just keep calling EVERYDAY and say nothing, and hang up when i answer.

I just called the number back, and they said they were Walka company offering walmart cards etc that I have won. Just don't answer the call and block it.

received this call twice today. called back both times,phone did not even ring once.???
