I come to ask for clarification, because the receipt of the readings says that the count of the readings is 25-30 days after the end of the billing period on receipt of the bill of water, comes only 24 from 18-2 to 13 -3 as I give the 25 to 30 day count, no longer enter the current receipt, the count, given by me which means that the company estimates the cubic meters of water, but makes another mistake, to my detriment, because at the current reading, the receipt comes to zero, at the next count, the company does the reading and then ignores the estimated 1667 meters + 9 meters (m3) gives 1676, as I gave the count on 18/03/03 2014 did not enter 1.677 (M3) without another subject thanked, explicit information on my subject, grateful for the attention 30-03-2014
