The caller asked if I wished to have my computer servicing continue for another 3 years and if I did nothing then $400 would be debited from my bank, I told him that I did not have a servicing arrangement. He asked me to hang up on him. I did not hang up on him but I waited until he, as far as I could tell, ended the call after a long wait. He said the name of the company he was calling from was "Kore". I am suspecting that this was a scam call.
