Información limitada: número móvil (Vodafone) listado como spam con solo 2 reportes oficiales en la base, aunque en los datos hay 6 comentarios repetidos. Los usuarios indican llamadas comerciales muy insistentes y también describen intentos de estafa mediante una "carta" de la luz que no les ha llegado, sugiriendo suplantación de la compañía eléctrica. Hay contradicción entre el contador de reportes y los comentarios; por precaución no responder y vigilar.

Likely purpose: estafa/suplantación relacionada con facturas de la luz (falsa "carta" de la luz)
