Aguas de Narixa has officially announced two customer service numbers, having introduced the system on April 1st as an experiment but without publicising it.
The first number is 900813810, which is for a number of functions, such as additions, deletions, changes of ownership and paying bills. This can be done from Monday to Friday 08:00 hours to 20:00. The same number can also be used for fault management and information 24 hours a day, 365 days a year.
A second number, 900813820, is for communicating meter readings, also for 365 days a year and at any time. Both numbers are free.
