As a consumer I find it absurd that this month April 9/4/2016 did not receive the invoice for the month of March, and calling the services blame the post office.
I do not agree that you are charged interest for late payment of the invoice when as a consumer I have the right up to 30 days after the date of the invoice to make the payment and after 5 days frighten you with a cut-off letter from which you charge another amount for the taxpayer to pay, amount the one that multiplied by the municipalities is worth Millions and they say that fears loss something is bad, but time will possibly tell you in the new elections to find a way to resolve the issue.
