Technical support scams are common worldwide, and scammers often use similar approaches to deceive innocent people. Typically, they impersonate companies like Apple, Microsoft, Google etc, and contact individuals about a computer virus, technical issue, or security concern. Their goal is to instill fear and urgency, prompting victims to seek their assistance or pay for fake services. The scammers offer to "fix" the issue and trick individuals into revealing personal information or use other tactics to steal their money. Globally, fake technical support scams have been reported in many countries including, Canada, United States, Ireland, United Kingdom, The Netherlands, Germany, Australia, New Zealand, India, and South Africa, among others. 

If you have fallen victim to a technical support scam, take these actions as soon as you can to minimize damage:

1. Contact your bank: Immediately contact your bank and inform them about all the transactions you have made. Keep screenshots and receipts ready, if any. Keep monitoring your account and report any questionable activity. 
2. Stop all communications with the scammer: As soon as you realize you have been scammed, stop communicating with the scammer. They might try to lure you into giving more money by pretending to help you.
3. Disconnect internet: If you have provided remote access to your device, it is important that you disconnect the internet to avoid any further loss. 
4. Check for suspicious software on your device: Uninstall any app you do not recognize and run a security scan using a trusted antivirus software.
5. Change your passwords: Change passwords for all important accounts, including banking and social media.
6. Gather evidence: Keep records of phone calls, emails, and text messages to provide to the relevant authorities for investigation and potential blocking of the money transfer.
7. Report the number on the Truecaller app: Since Truecaller is a community-based platform, reporting helps warn and protect others from scammers.

Scammers impersonate reputable tech companies to gain trust and then use fear or urgency to deceive individuals into paying money or granting remote access to their devices to fix an issue that does not exist. They often contact people about a virus infecting their device or their system being hacked. It is crucial to stay vigilant and not fall for their fabricated scenarios. Also, installing apps like Truecaller is a reliable way to block spam calls and filter fraudulent messages through their SMS fraud detection feature.
