I bought the pack of 3 because of the better deal and free shipping. It arrived on time but I am not noticing that the package did not come with any information about my Order. After using it for almost 2 months I have seen no results. I decided to return it to get my money back. I contacted the customer service to see how to return it since there is no information else where. It says the workers will usually get back to you within 24 hours. They never did. I contacted them again and still no answer. I'm not sure whether to send it back or keep it but either way is a waste of money. I would not recommend this product to anyone considering it doesn't work and their customer service is bad.
