The service was sub-par. We have been trying to resolve an issue with the billing department since 2012. Many attempts to contact and resolve has ended up back at point A, just trying to get a hold of them. Calling the customer service extension will get you an endlessly ringing phone with no hope of hearing a voice, then IF someone answers (on rare occasion), they tell you what you want to hear and then never follow through, putting you again back at point A, just trying to get a hold of someone who will take care of business.
