Why Do Spam Calls Happen?
Spam calls are generally placed for the purpose of tricking recipients into providing personal information or money. Scammers may use phone numbers from different sources and categories, including:

Many of these numbers are disguised to appear legitimate, such as pretending to be from official institutions like banks, HMRC (Her Majesty’s Revenue and Customs), or even local authorities. The goal is to create a sense of urgency and convince individuals to share personal information or make payments.
