Fans queued for hours for the store on London's Old Street to open its doors last week, where the star is selling his limited edition merchandise, including tops, jumpers, and hats featuring Gothic font used by artist Cali Thornhill DeWitt.
"I queued up for hours to get in to Kanye's shop and I was so excited to get one of the limited edition London T-shirts," one customer moaned, according to The Sun.
"However, I'm not so excited about my purchase now I know it's basically a cheap T-shirt with a print. I'm gutted, to be honest."
Yeezy's name or his album title, The Life of Pablo, is spelled out on many of the items and supporters have been waiting weeks to get their hands on them.
The cheap t-shirts are available on hivis.co.uk and Kanye is yet to comment on the accusations he's duped fans.
Carlos Rico, 19, from Essex, braved the rain and waited for 15 HOURS for the new shop to open in London.
"I'm a big Kanye West fan and a big fan of fashion. So Kanye West and fashion in London? You've just got to go," he told the Press Association. "I wanted to be at the front of the queue to make sure I get my stuff.
"I just love his music and everything he stands for. Kanye is like Marmite, you love him or you hate him."
