apparently I went to a wrong website. and crashed safari. there is a number to call 1-855-509-5719 which I called however it sounded very sketchy as there was a lot of background noise. the man asked for my number and I said I'd call back. has anyone experienced this or know what I need to do? I'm not really trusting this. The full message is: Due to third party application in your phone, IOS is crashed Contact Support for Immediate Fix +1-855-509-5719.
