I found a 5 year old thread with this topic, but it's closed and no one ever had an answer. I'm hoping maybe now someone does have an answer because this situation is freaking me out! Although, weirdly, it made me feel better to know it's happening to other people...
Here's what happens: Whenever I call a legitimate banking number (both my credit card company and an investment firm I use), I end up with a "missed call" notification. But my phone never rang during the call! It's clearly a spam call, but I don't even know when they called during the call I was on with my actual banking company.
Since I don't even hear the call happen, I've never answered one and they never leave a voice mail. So why is it showing up? Why are they calling?
I'm on a Google Pixel 7a (many of the people in the older thread seemed to be on Pixel phones) and I have anti-virus software on it. When I run a scan, it doesn't show any viruses.
I guess what I'm wondering is, technologically, can this mystery "missed call" somehow be tapping into my phone during my conversation with my legitimate bank and hearing the information I give them to verify my identity? Is this a thing? Is there a way spam phone numbers can listen in on your phone calls if they call while you're on the line with someone else?
I'm hoping someone can shed some light on this. Mostly when you search up "spam calls during banking phone calls" you just get info on regular spam calls, like the kind that you can block. Not these "missed call" notifications that show up during a regular banking call and I never even have the option of blocking them because they never actually ring.
I am able to block them in my call history after the fact, but since it's a different number every time I call a financial company, that seems hopeless.
