Phishing Tactics: Scammers often use this number to pretend to be from well-known financial institutions, attempting to collect sensitive information such as account numbers, passwords, or personal identification details. These calls are typically automated and do not leave a voicemail, hoping to trick you into calling back and interacting with a live agent.

02080448944

Loan Scam Tactics: The scammer will promise a loan that never materializes, often claiming that the upfront fee is necessary for administrative purposes. Once the fee is paid, the victim never receives the loan and loses their money.

PPI Claim Scam Tactics: While some legitimate firms offer PPI claim services, this number has been used by scammers who charge high fees for very little work. In many cases, the claim doesn’t go through, and the individual never receives any money back.
Protect Yourself: If you’ve already received a PPI refund, or you believe you may be entitled to one, you can directly contact your bank or insurance provider to inquire about your options. Avoid paying anyone to handle your claim.

How to Protect Yourself from Spam Calls

- Report Spam Calls: If you receive a suspicious call, report it to the authorities or your mobile service provider. The more reports they receive, the quicker they can take action against scammers.
- Use Call Screening: If you’re unsure about a number, let the call go to voicemail. Scammers rarely leave messages, so if the call was important, the legitimate caller will leave a voicemail.
- Verify Contact Information: Always independently verify the contact information provided by callers, especially if they’re offering services, loans, or prizes.
