Horribly overcharged / dangerous pharmacist assist

On 25/12/2015 my father went to purchase a small botthe of Povidone Iodine (100ml). They charged him for 1000 ml. Ten times overcharged. And no one there to sort it out. I am at work from 7 in the morning till 6 in the afternoon daily, so I cannot get there when management is available.

The \pharmacist on duty insisted that paynamol is the generic
