Why Are Telemarketing Calls Such a Problem in the UK? 

Despite regulations, nuisance calls remain widespread in the UK: 

  • High volume: Millions of unwanted calls are made daily, many targeting seniors. 

  • Scams disguised as sales: Fraudsters often pretend to sell services, hiding their real intent. 

  • Elderly vulnerability: Older adults may feel pressured or confused by aggressive sales tactics. 

  • Limited impact of TPS: While useful, TPS cannot block overseas or fraudulent callers. 

Summary: Telemarketing remains a problem in the UK due to overseas calls, scam disguises, elderly vulnerability, and TPS limitations.
