AI Analysis

Limited information but with clear spam patterns. The number +34621417556 has been reported multiple times for making unwanted calls, posing as Naturgy representatives. Tactics include: (1) Requesting email to send invoices, (2) Offering cheaper rate or contract changes, (3) Lying about contract or distributor status to create urgency. Some users report calls being abruptly cut off when the claims are questioned. SMS with links to proceed have also been reported, which is highly suspicious and potentially harmful.

Likely purpose: To scam or deceive users into providing personal info (such as emails) or selling energy service contracts under false pretenses.

Te llaman diciendo que son de Naturgy, te preguntan por tu correo electrónico para enviarte las facturas, te dicen que la otra comercializadora es más cara y si lo quieres cambiar de nuevo, te dicen que un momento y al poco se corta. Te mandan un sms para que continúes con el enlace que te envían

Te dicen que la distribuidora ha paralizado la nueva contratación porque la tarifa es más alta y cuando le dices que es más baja y que ya tienes el contrato te cuelgan.

Llaman diciendo que son Naturgy y que al hacer cambio de titularidad te han subido la tarifa, y que ellos lo han parado para poder ponerte la mejor tarifa. Esto es falso pq cuando me han llamado el cambio de titularidad ya estaba solucionado hace varios días
