I'm writing this in order to warn prospective customers. I've had a very bad experience with Navi Organics. I tried to leave a review on their website describing that experience but it has been blocked. There is no possible explanation for this (such as offensive language) other than that it was a negative review. The Navi Organics website has hundreds of positive reviews but I have been unable to find a single negative one so I believe they are systematically blocking them. I think this practice is dangerous and very unfair to customers so I will be making a report to Trading Standards and The Competition and Markets Authority.
