Future Money Personal Loan — Did not return my old PDC even after 2 years after PDC swap

Address: Bangalore, Karnataka

Hi,
I had taken personal Loan from Future Money in July 2008. In July 2009 i asked them to swap my PDC from ICICI bank to SBH. Which was excepted and they collected my SBH PDC and promised me that i will receive my ICICI bank's balance PDC after 1st successful strike to my SBH account. Its more than 2 years now and i have given countless complaints to their Customer Care and Branch office there is no response from them. Every time they tell the same statement."Sorry for inconvenience sir. we will raise a request on priority.". I am fed up now please suggest me what can i do now.
Regards
Ravikiran
