Misleading advertising

I have recently received their 2021 booklet via the newspaper and it had a special on their laptops. I then proceeded to their website to purchase the laptop and upon searching for it the price did not match the advertised price. I then contacted support and spoke to Stewart who first told me the item was out of stock I then told him that I can see the item online, he then told me that the price has been updated and I need to look at the new catalogue which happens to be the exact same one I have but the laptop price has just increased? He then refused to assist me further, I then contacted support who as not even bothered to contact me back. Pathetic service and false and misleading adverti*****ts!!
