Kylie Jenner was understandably upset when news hit the web, claiming her cosmetics company had been given an "F" rating by the Better Business Bureau.

In response to the bad press, the 18-year-old Keeping Up With the Kardashians star spoke to fans on her app.

"I’ve sold millions of lip kits and any complaint we’ve received to date has been addressed in a timely manner. I’m sick and tired of people coming for my business. I love everything about Kylie Cosmetics and I will do anything in my power to protect and improve it every day and make you guys happy," Jenner wrote on her app on Wednesday, according to a report by Us Weekly.

"I don’t want to respond to the haters but you guys deserve an answer and to know the facts," she continued. "I love you and apologize to anyone who felt the urge to complain and didn’t receive the service they deserve."

The Better Business Bureau claimed they received at least 133 complaints from customers last year who expressed grievances over delivery issues and problems with Jenner's product. However, after the review was released, the BBB changed the "F" rating to "no rating," explaining that another rating will be given once the "current review is complete."

"You guys are the reason I keep going and I’m motivated every day to make Kylie Cosmetics the best it can be," she wrote Wednesday. "I’m continuing to learn and I just want to make everyone happy. Because so many of you spoke out, I’m excited to tell you that the Better Business Bureau has looked at the facts and changed the rating."
