Timbl Broadband — Refund for new connection cancellation

Address:	13/4 Marla, Model Town, Gurugram, Haryana 122001
Website:	www.timbl.co.in

I applied for new connection and then cancelled it but "Timbl Broadband" hasn't provided me with the refund of 824 rupees, have emailed them several times but no reply still.
Every time i call them they say that resolution will be provided shortly, a ticket id is generated with every call with the resolution date and the problem is never solved on the resolution date.
I need my refund on immediate basis.
