Yes you could be dealing with someone who takes the inner of the pill and puts random substances inside. Now I can help you just tell me the item #. Did it state new? You should have told them that they never stated the pills were going to be loosely processed. They misrepresented there product. Also you risk contamination or being sold an expired product!

Do not contact the user first contact the chat. Tell them you were never told the pills were removed from their packaging and this poses a liability and safety issues. Tell them you do not understand why they would remove the pills unless they were trying to sell expired pills or tampered pills. Also tell them you contacted GlaxoSmithKline and they told you never to consume open products.
