I previously used sleek hair and was satisfied. On my most recent order, I received a confirmation the day I ordered. Seven days later, I get an email saying they put my credit card order is on hold, and I must use Paypal. I used the same credit card and shipping address as before. I called Sleek hair and was put on hold. After waiting, I was then put on an answering machine and told to leave a message. When they returned my email, they were completely unapologetic. I cancelled my order and will not use sleek hair again.
