Dhani Shopping - Expiry date

Since there is no mention of expiry date on any of their products, so it is impossible to order or buy the same, as they all are under 'non-returnable' policy, also after contacting the customer care about the same, he said" neither I can forward your complaint nor provide you with the mobile number of any of his higher authorities, only help he can give is that he can take this as a feedback and share with the company. When you do know about the shelf life of the product, how can you order it online, also when all the leading health sites do write about the expiry date [informed decision], then why do they refrain from the same, or there must be a hidden scam going on.
