Called demanding money for a security package, dating back several years, to the tune of ~$4000
took control of my computer and threatened debt collectors

Caller: Bob Wilson from Secure Shop Network Security Services - apparently

Called stating that if I didn't cancel my network security package which I purchased 3 yrs ago, they were going to debit my account for $800. Tried to take control of my computer by asking me to put a cancelation code into my computer's command prompt
