NIIT — False commitment of course

Address:

Mumbai Suburban, Maharashtra

I have inquired about a course at NIIT Andheri east, Mumbai for PHP, MySQL, Photoshop & Flash. They promised me a course which will be for 6 hours every sunday where all 4 softwares will be started together and they said the course was customized for me. They took 10K cash and 6.5K as PDC's for the course. They called me on March 28 2010 for joining of course but when I went there the representative told me that there was no such batch alloted and asked me to come next Sunday. She also told that she will be confirming me about the same on 1st to tell me the time but there was no response from them. I called them on 1st and 2nd but nobody picked the call. Then I called on 3rd and the girl asked me to wait for 30mins and told that she will be calling me back but after that I called called her when she didnt respond. SOme other girl picked up saying that the concerned person is not there. I asked her about the class , she told there was no such class alloted. when I asked her to return my money she told me to contact the concerned person. When I asked her for the number of that concerned person she refused to give me. I told her I will come on Sunday and take my money back over which she replied that there wont be any one available on Sunday and asked me to come on Monday. After which I searched on google so that I could register a complaint at there website and I found that there were unlimited complaints against the institute and I dont find it worth wasting my money now.
What can I do if I want my money back. I have even read instances about NIIT not returning money.
Can I file a consumer complaint against NIIT in this case. I have already stopped the PDC's but they still have my 10K. If I can file the complaint, then what is the procedure
Please help
