If you want to comparison shop high speed internet access, for example, you have to get a quote from each provider, as the rate is based on your estrato. Things have gotten better recently but until the last couple years, those rates were just in a big binder in the office, not something you could just look up online. I feel it hurts competition - providers can’t just advertise a monthly rate - and I can only imagine the added complexity in billing systems, etc, that ultimately is passed on to the consumer.
