I keep getting a call from 0404 553 475.. When I call back the number, I get a recording that "the mobile number you are calling has incoming caller restrictions." When I answer the call, I also get a recording "Your internet provider noticed that your bla bla bla and your internet will be disconnected...?"

Phoned my internet provider who advised me that they would be texting, emailing or calling from 02 number.:-(
