Excellent customer service, clearly care for their customers. I did the free trial and enjoyed the product. I forgot to cancel the trial and was charged full price for the product. Without any questions asked you can go in and get a refund from their site, it's not hidden they really care about customers! At the same time, I saved a lot of money on studying at the Brilliant website thanks to the discounts that I found on the Revieweek website - https://revieweek.com/promocode/education/brilliant/. I advise you to try it too!
