      Lavit Singh's Review Sourced from Google

      This company is completely fake and untrustworthy. I spent 150+ hours working on their website, but in the end, they refused to pay even a single penny. :warning: Warning to other freelancers: do not trust this client. They waste time, exploit efforts, and do not respect the work. Stay away to save your valuable time and energy.
