Is it possible to reapply again after being denied with a tourist visa?

I asked for an agency to help me out get a L type one because of my busy schedule,they handled my passport for two months and just now they told me my application is denied,i was so dissappointed paying them a lot and no one was released. i asked them why, they told me my itr bank statement was questionable the fact that i did not know it was needed for the application,They just got my id's, passport, certification from where i work and recent picture. I really want to visit beijing but now all of this are hopeless. I really would like to travel in beijing for atleast five days so i could use my vacation leave that i filed this month. I am so really disappointed with the agencies way of supporting their client.
