I got a call from this number +34 628 275 82, as someone who lives in the US. This Spanish number was a bot that told me to call this number:
844-922-9930
They are predating on elderly and vulnerable people by offering help with back taxes. They claim to be out of California, but they are definitely not legit. They don’t block you either, so you can call this number all you want. I already have 20 times under my belt, and counting.
