Hyland Cell Salt Kali Phos 6x 500 tabs

The product description indicates this is for 6 (six) bottles. I only received one bottle of the product

I received the product in mail, my wife had ordered under her account, but in taking it I received some really severe stomach pain, feels like someone is pumping up my stomach and it last about 30-40 minutes.. not sure if it's allergy related I am not diagnosed with any allergies, but definitely being caused by these cell salts. I say this because every time I take some the same thing happens.... didn't have this before in my life... just with this stuff. maybe take smaller than recommended amount maybe just 1 tab.
