This place stays in business because of idiots like you, that don't pay attention when the guy at the front desk is price gauging the customers, and hiring all kinds of shade tree machanics.
They expect you to complain after the issue is not resolved, and will refuse to take responsibility for there flaky diagnosis. Causeing you more problems then you had to begin with. Another scam company taking advantage of the. Consumer.
Stay miles away from them!!!
