Make your customer support on whatsapp. "Drop us a message to change your order". Allow ordering/enquiries over whatsapp.

Send 2 factor verification pins over whatsapp - it is more reliable than SMS and generally there is a better 1:1 mapping between whatsapp accounts and real humans than phone numbers, so it is a good anti-spam or good way to distribute "first month free" type deals whilst keeping abuse low.

Obviously make sure all URL's have info cards properly rendered in Whatsapp for good share-ability.
