The only mistake from my side was going to them to enquire about the courses offered there.
They kept on calling me after that even when I told them that I'm not interested. It was so annoying.

Today I got a call from them. When I told them that I started working, that lady asked me whether any of my friends who are unemployed wants to join there. When I told her all my friends are working now, that lady arrogantly hung the phone up on me. It was a very very unprofessional thing to do from their side. I am never ever going to recommend this place to anyone I know!!
