Incredible Connection misleading advertising !!

I was searching for power banks online and Incredible Connection came up, advertising 5000mAh. 8000mAh and 10000mAh power banks. I drove all the way to Cresta and they didn't have ANY in stock. Indeed the salesman had no idea why these were advertised as he was unaware that these had ever been in stock. Very unprofessional and misleading to the public.
