Insulting customers

We are very disappointed with the terrible attitude of the one male consultant. He insulated us when asking for assistance regarding a product bought at the store and refuses to assist us. He told us we should come back in the week to speak to the manager. <br> <br> We brought a screen protector which was chipped and the oleo phobic coating wasn't covering the entire screen and had constant streaks. <br> <br> We feel as a customer that the consultant should provide assistance rather than insults.
