Treesha Desire Infotech Solutions Software Developer interview questions

I applied online.Then they asked me to come to some placement company location.there interviewer asked me about Java, for which i was applying. Ques were preety simple. just basics. then they said they'll give me problem statement and i've to submit them solution. for this they charged 100 rs. when i checked my mail, i realized that i've paid for registering with their placement agency "SULABHATA". They didn't speak a word earlier about this agency. after submitting solution, after a month or so they told me that i am not being selected. and till date i have not received any placement calls from their company also. i would this was just a way to fool people...
