HDFC Bank — 12k deducted from my savings account

Am a Wipro employee US and I did open this HDFC account for my reimbursement account. My savings account did not have money but then current account has. Transferred amount of like 12k from my current account to savings account [protected] . And immdetaly the entire amount got deducted. I wantto know the reason and I was thinking of maintaining and opening an NRE account with HDFC but am really disappointed with this. Please revert back the money soon And please let me know if you can revert this account for me else I would prefer close this account.
