The call appears to be a generic sales or phishing outreach that offers a vague "consultant" callback. Since you never initiated an enquiry, treat the offer with suspicion and avoid providing personal data. Let the call go to voicemail, then verify any claimed company by independent means before returning the call. If the number persists, consider blocking it and reporting it to your telecom provider or a consumer protection agency. Stay alert for similar unsolicited contacts that use vague language to prompt a response; they often aim to harvest information or sell unnecessary services.
When I returned the call, the only thing I heard was “your enquiry isn’t important, a consultant will call you back shortly”. That happened around 10:30 am, and oddly I haven’t submitted any queries lately, you know.
