Skyfi worst service

This is a company where you pay for the service for a month.But only get 3 day a week service and the other 4 day nothing.The company don't care if they have service or not they just leave it and only reply to a email 8ncethe service is up and running again.You pay for 4mg line and get 2 mg service. You send them the email with the proof and they do nothing about it.Managers don't bother calling u back after sending emails or leaving them messages. So can someone please tell me why people are still using them.
