The customer service was really good. I got the Groupon eyelashes and they looked good the first day except that about 3 of them where really far up my eyelid and not connected to my natural lashes at all. The extensions started falling out the second day and third and so on. I tried my best to take care of them but they wouldn't stay on. Now it's the 5th day and I have huge gaps that do not look good at all.
