If I could give you guys ZERO starts, I would. I purchased lightener that is supposed to lift up to 9 levels & it did absolutely nothing. I followed the instructions and did everything correctly. Called for a refund & was told I could only receive a credit. Why would I wanna spend anymore money with you, when your products clearly don't work? & whoever the employee was that I spoke to on the phone needs retrained in manners because she had a smart $#*! mouth. If I could smack someone through a phone call I would.
