BE CAREFUL ,DO NOT BUY ANY PACKAGES.
It used to be a good company, teachers are very good, but be careful! They have just changed recently, and will cancel all your lessons without notice! Customer services have hired an army of mean people. Just said it has been expired and ask you to buy more lessons instead. They apology a lot, but half of the lessons I bought are wasted, worth 400 USD. Do not buy their lesson packages, you will regret! This is a company with no credit.
