My rewards code is BRC578. I've tried to contact Iherb three times by email without solution/ answer. My rewards credits have dropped from US$ 7.83 (on 07/02/2019) to US$ -23.18 (on 07/07/2019). When these changes on the rewards credit have happened, almost 10 dolars were missing on the first time and right after that more US$ 7.5 were missing (61.22 to 53.72= 7.5). At the moment, at least US$ 17 are missing and the available rewards credit should be US$ 17 plus all the money earned after that US$ 11.19, totalizing US$ 28.19. I want all my rewards US$ US$ 28.19.
