Found this fake Yahoo support number (855) 999-8045 via bing’ing yahoo support. Turned out to be their pop-up number. Didn’t ask for error codes, so I described some bland pop-up. Guy told me to go to a tinyurl(/tv355 I believe) site that force downloads a remote access tool & asked me for my user/password. Called back, got a different guy & was given TechFeeders, https:/techfeeders.com, number (listed above) as his direct line. Enjoy!
I played them the headcrab zombie sounds from half life on full volume
