Ideal Image review: Coolsculpting

I didn't really have that much fat to get rid of and the consultant told me I would need 2 units and it would be 1700. Then she told me to go see the "nurse" then that lady told me 4 units would be better and it would be 2400. I went in for my appointment and the lady doing it acted like she wasn't use to doing it also what they told would happen afterwards didn't happen (like my stomach would be red, cold and where the machine was would look like a stick of butter) they said it would take 90 to see results and I don't see any change whatsoever. I honestly don't think that lady did it correctly.
