HDFC Savings A/C
Disable of my D-mat linked Savings A/c

I have a D-mat (A/c No.20080882) and a linked saving A/c with netbanking facility (A/c No.0881000224173) which has been disabled hence I am unable to do transactions online in this A/C.There is no way to contact the Bank as the nos. given on their website are old nos. Can I know why this account has been disabled?

I would request through this site to HDFC Bank to enable my aforementioned account or else send the new password at my mailing address.
