  • Advanced: focused on customers who require more personalized attention than that included by default in the standard contracted services.

These services are provided remotely, with a 24×7 level of attention.


Serving 2,200 Standard management clients and 55 Premium clients in the provinces of Andalusia, Extremadura, Ceuta, Melilla and the Canary Islands.
