Selling used products

Yesterday, 24th June 2018, we bought studio line hair wax. This was bought from Clicks stores in Pavilion. This morning I opened the wax, and someone had already opened it and taken a finger full of the wax out. The imprint of the person's finger was quite distinct as they have taken out a considerable amount. Wax is expensive, and I wouldn't expect this from such a big store such as Clicks. I am disgusted and have lost all respect for this store. We buy alot of our personal products from their, and now we are not sure just have safe those products are to use... I will NEVER be buying anything from them again.
