With reference to the communication # CPC/0809/I2/901699588 dated 31/03/2010 from CPC and PAN ATOPS0465J, I have sent 3 letters for the refund, but havent heared anything back.

DO THEY ACTUALLY SEE YOUR GRIEVANCES??? Is there any other means to contact Centralized Processing Center(CPC), Income Tax Department, Bangalore-560100 other than sending ordinary post. Please let me know.
