1 to 2 years ago, while i was surfing online, there was a pop up window stating a malware attack. When i clicked in, there is an option to contact the technician support so i just went ahead. They mentioned they need to access through my computer to install the software and i allowed them. It costs $200 for a 2 years service ( no auto renewal was mentioned), so i just paid the technician and receipt was provided since they are Singapore based. Even though i felt bit cheated after purchasing their services knowing that my computer might not even have a problem ( after googling), thinking that after the 2 years i won't be bothered by them, i just let it be. Just today, they called and asked whether i would like to continue with their service and i told them no. They told me that since it was an auto renewal of the services, if i were to cancel, i have to pay the remaining $300USD. I questioned them why is my card detail still with them and told them to cancel the service if not i will make a police report. So instead of cancelling, now they threaten me, told me they will not cancel the service and let it charge another 300 to 800 USD. They hanged up my phone and told me to wait for the charges.
Immediately, i called to cancel my card and make a police report.
From this incident, i have learnt not to provide any information and to google before accepting this offer.
Anyone can be a victim of scam but don't let it the incident fear you, be calm and do the necessary things.
