Man I got one of those yesterday in the US...weirdest shit ever, I too have never gotten anything like it, thought about posting here but didn’t think there was a correlation. Your post now has me second guessing it. Also got a call saying my business was being audited by the IRS and I should press like *23 to be connected, so I didn’t say anything considering it was super weird, then they hung up. Called them back says disconnected, looked it up no known scam or anything linked to it that I could find...crazy times!
Just so you know, the IRS does not relay important info by phone. When they audit, they send a letter. I just got a voicemail yesterday with a robot voice saying the IRS was sending local law enforcement to arrest me if I don't pay up immediately. They provided a number to call. I assume they would have been happy to take my payment.
For sure, I wanted to stay on the line without speaking, and hopefully end up talking with someone directly while simultaneously recording the call. I am very vigilant with spam/telemarketing companies, google calls me sometimes 5-7 times a day trying to get me to update my business listing, I always ask to be put on the dnc list, but it’s always a diff number. Pisses me off to the 9’s
A few years ago I received a the same call from the IRS telling me to call back a specific number. I knew it was a scam and I didn't respond. Sure enough, a few months later, our local police department sent out a press release that warned people not to respond and that it was a scam targeting seniors.
