This guy with a strong Indian accent called my mum up, (shes not the account holder of singtel) and without any form of verification, they said there was a routine internet problem. My mum was irritated as the routine was very different from what singtel usually does (they ask to talk directly to the account holder), and told the guy off, but he was still persistent, however he had an audibly irritated tone. He answered rudely, saying that this is why singtel hired me for the IT department. he then asked to press windows r, which we did at first, but then when he asked to key something in, we immediately cancelled it and told him to call the account holder himself if he was still persistent.
