Said he was with PC Solutions and wanted to let me know my computer was compromised. I told him to put me on the do not call list and he replied "up to you ma'am" and hung up.
Called at my work and claimed to be from Microsoft. Someone with a thick Indian accent said he would tell me what was wrong with my computer. I asked for his number to call him back and he got upset and asked me what my problem was. Eventually he hung up.
