bad service! I respond to one in ten calls, when they do they say that if they don't occupy them and turn me to another number, which happens to be, the person is currently busy please stay on the line, then say they have no free . Recall saying that the number does not answer and so I get? "and what can I do, try to call back" then I ask for the number so as to call it "look for the number from the internet", but sorry I am a customer does not exist that when I call to know something I am given an answer like this!
