Expert Opinion

A pushy caller claimed to discuss your electric bill and left a 866‑526‑7448 number, refusing to take no for an answer. The pattern—multiple back‑to‑back rings, a single voicemail, and a name that shifts between Amber, Rebecca, and Shannon—matches typical high‑volume telemarketing scripts used by NTherm, an energy reseller with a B‑rating on the BBB. Recipients should add the number to their block list, register the line with the national Do Not Call Registry, and file a complaint with the BBB or FTC if the calls persist. Keeping a call log helps prove repeated harassment, and asking the caller to remove you from their call list can trigger a 72‑hour removal window.
