You are going to want to have you computer checked for trojan/virus as the caller probably left some nasties on your computer after you gave them access to it.
There are free scanners you can download and run, MalwareBytes is a very good one.
Called Sunday at 6:30 in the evening. Am in Toronto and picked up this supposedly local call as I was expecting a call. Call display said 'Private". Was the Bahama cruise take a survey scam/Fraud. This one has been going on for years.
