iHerb review: Instant reward credits aren't instant & customer service doesn't care

They are great with shipping and refunding damaged items. However, it is getting very problematic concerning simply being able to leave product reviews and get the advertised 'instant' $1 per item. I never had issues in the past, but whenever I leave a review, it is not instant anymore, and I have to wait at least 48 hours. It is frustrating working with the customer service bot to then get to a real human and the person I have received messages from has left me in the dark since last responding, seemingly not doing anything yet to get me the credits. It is not clear what has changed, but the credits used to be instant and not requiring 48 hours to approve. It is frustrating because the customer service is now so poor when you actually need to contact a human versus how it used to be not too long ago. I'm not sure what happened, but just this issue makes me not want to order anymore. It's a simple thing, but I have chronic health issues and am autistic, and just trying to get some clarity on why this issue is happening so often and get discounts on my purchase so I can save a little bit of money being on a tight budget is making me waste precious time and energy trying to talk to customer service and still having to wait endlessly.
