Knowledgewoods Consulting — pmp certification

This is regarding my registration with knowledgewoods for PMP classroom training that was supposed to happen in July in Hyderabad.
However, one day before the training was supposed to happen, I have received a call saying the sessions have been cancelled.
I have not received any further information about it until mid August.
Even if it would be conducted, i would'nt be able to attend the classes due to other priorities. Hence i have asked for a refund of the 12500 that i have paid for the class.
One person from the company has assured the money will be returned but the money never came back even after repeated followups. Finally the same guy responded saying he quit from the company but gave me few email ids and numbers who will be able to help.
But none of the persons from that office respond to the repeated emails that i have been sending. I feel helpless as i do not know about any other numbers or forum where i can complain about them.
