Clueless Staff and defective products at Hi store

I went to the Hi store at Gateway mall, hoping to leave with a state of the art laptop in my possession. The store had a limited range because it was so small, so I came in and told the male assistant I found there that I must absolutely leave with a laptop with specific minimum of requirements. The man assisting me was absolutely clueless on laptops, it was nearly as if it was his first time meeting someone who actually asked him about the models. I asked basic questions which he absolutely blundered, so that was disappointing. I even had to ask him for a moment alone so I can just Google the device that drew my attention because his presence was essentially a waste of time. After researching, I bought a wonderful laptop that I'm happy with, and disappointingly, a Volkano ring light set that didn't work at all. Although I'm happy with the laptop, the staff did nothing to educate me on the best choice for me, and the broken product all but cemented the fact that I cannot return to this store. Please train your staff about the products and check products for quality.
