Don’t waste your time picking it up; let it ring. Unsolicited calls from numbers like +17154968964 often turn out to be market‑research surveys, especially when the caller identifies as Dynata. If you’re not interested, let the call go to voicemail, then block the number or add it to your phone’s do‑not‑call list. You can also register with the national Do Not Call Registry to reduce future outreach. For a one‑time opt‑out, visit Dynata’s website and follow their unsubscribe instructions. Keep an eye on any follow‑up emails or texts, and never share personal or financial details unless you’ve verified the caller’s legitimacy.
