Gracias por compartir su experiencia con nuestro experto en atención al cliente de Guardian, César. He enviado su reseña a nuestro equipo directivo para reconocer su excelente servicio.
I'm still a pretty new customer. In previous calls, problems kept coming up and it was very confusing. The person I spoke with was polite and that made a big difference. Today, everything went smooth. Thank you.
