They stiff the tutors
I sign a contract and pre-paid for 20 sessions. The first tutor they sent wanted us to pay him and quit when he didn't get paid. The second (she was wonderful) tried repeatedly to get paid, but was stiffed by this company. she quit also. They never answer their phone or emails but then call you back (at the most inconvenient time!). I feel like I've been taken. This is a warning, do NOT use this service!
