Phishing Scam Impersonation Scam
Received a call from the above number, claiming to be from singtel technical department. Mentioned that my Internet speed is getting slower due to unauthorised users, and asked me to use the run function in my laptop to generate data to provide them. I am not a singtel user and told them so towards end of the call, and they claimed that all WiFi and call lines are managed by singtel in Singapore.
