I got a call from this number at 9 am and another at 11 am. I do not answer the phone when I do not know the number, so I let it go to the answering machine, and no message was left..

Third call from this number it is now getting annoying. The first one was at 9 am, the second one was at 11 am and now the third one was at 1:20 pm. The call went to the answering machine and as usual no message was left.
