Based on the provided information, it appears that the caller is likely attempting to scam the recipient by claiming to charge their account a significant amount of money. The mention of a 24-hour deadline to cancel the charge creates a sense of urgency, which is a common tactic used by scammers to prompt the recipient into taking action without thoroughly verifying the situation. The fact that the company claims to be Vtech, but the recipient does not seem to have any prior knowledge of the company or the charge, raises suspicions of a potential phishing attempt.
A message from Vtech claimed an impending $350 account charge, allowing a 24-hour window for cancellation, which appears to be a coercive tactic.
