Why Is It Spam?
The nature of the call often involves high-pressure sales tactics, and the operators can be pushy in their attempts to secure a sale. Moreover, the company behind this number may be involved in questionable marketing practices, such as using personal information without consent or engaging in unsolicited cold calling.

Why Is It Spam?
The primary purpose of these calls is to trick you into providing sensitive information, such as your bank details, or even to ask for a fee to process the “refund.” These calls may even impersonate official bodies, creating a false sense of urgency to compel the recipient to act quickly.
