No Customer Reviews or easily Accessible Space to Review on any Products on Website

I bought a "health" product from wellness warehouse. the service was good with a fast delivery turnaround. I experienced some adverse effects from the product and tried to return it for an exchange without success. The reason for the 2 stars is that there is no place to write a review easily of the product, nor any product on the website and thereby potentially warning new customers. I had another product, same brand as purchased from wellness, but directly from the website and received a refund without issues. I also have another order, still same brand, from wellness on the way, but will be logging a return as soon as its received to avoid a similar situation.
