Got another one of these calls today. This time I tried to waste as much of their time as possible. After the general pre amble I was directed to computer management > event viewer > admin events. I was told that this was the computer brain and these were malware errors, lol! I was then directed to
www.teamviewer.com and asked to download the remote access software.
During this we chatted about the weather in India, the best tourist sites near New Dehli, learning new languages, London, etc. My computer also BSOD, my internet was very slow and I kept forgetting what we were doing; all in the aid of slowing the process.
Obviously, I wasn't going to download the software, so I pretended my mobile was ringing, and said I would be back in a minute.
When I came back after lunch, they had gone.
However, next time I might use translate.google.com to explain to them why I am wasting their time, in Hindi. (google translate has a spoken version. not sure how good it is though.)
