I understand that the image is correctly showing as 1 item_package_quantity of 172g.
In this case, it seems like buyer has misunderstood the quantity of what they might be receiving.
However, we understand that you have correctly shipped your product and we see that you have shipped the product in bundles from Thailand to Bahrain.
We really appreciate your efforts in providing the best services for your customers.
We understand that lot of expenses are involved in shipping the product from one country to another and giving a refund is not really an option. Also, since all the details are clearly mentioned on the detail page, the error lies on behalf of the buyer.
