I bought the Vitamin C Serum for my 80 year old mother in the nursing home. While on my visit (9 hours away) I gave her this as part of her Christmas gift. Since she is unable to apply it to her own face, I opened the box and when I tried to pump, nothing came out. The pump is defective so I contacted customer service. I finally heard back when I was back in Florida. I was then told I need to send the item back in the original package for a replacement. I explained that my mother is paralyzed and not able to do anything, let alone pack the product and send back. I will not be back to see her for 4 weeks. Needless to say, I will never buy Kiehls again. I have been a loyal customer for 5 years. Really bad customer service. Lowest rating I can possibly give.
