Game Lacks Intergrity

I am really ****ed off with Game Pavilion, floor manager, Shane. We responded to an advert which we found on Game website brochure for a laptop. It stated it was an i7, 16GB ram, 1TB SSD for R12999. It is an MSI gaming laptop. We called and they had two in stock. We went the next day and bought both laptops, one for my wife, who is a writer and the other for me. The salesman,took our trolley and went and fetched it. I asked him about extended warranty and he said Game does not offer it anymore. My wife asked him if it looks like the i7 on display and he said yes. We paid and left. Upon arriving home, My son-in-law who is an IT technician told us that its an i5 and not and i7. The advert clearly states that its an i7 but nobody seems to read or understand the advert. I sent the advert many times to game and the call centre but "literacy" seems to be a problem. I even sent the advert to the floor manager, Shane and he being a manager lacks integrity and knowledge of how to speak to a customer. He was of no help to us except his arrogance. We have been shopping at Game for over 50 years and I am sure some of the staff were not even born. It is sad to see how Game has deteriorated. All I am asking for you to see the advert and give us what we paid for. How difficult is it to understand a simple thing like this. We haven't used it for over a week now until this matter is resolved. Please find enclosed the advert. U can also go on your website and check for the electronic advert. Disgusted Customer
