Guy with Indian accent, claimed to be from the "Customer Service Department at 'Geeks' ", whatever that is - I guess he believed that would grant him some form of legitimacy. I didn't engage with him, but this had all the background sounds of a very busy call center. My guess is that they were probably going to tell me something was wrong with my PC, or I needed to run one of their (ransomware) programs, or something. Called the number back after he hung up out of curiosity and got an out of service message.
