[Resolved]  HDFC Bank — call center unable to help

hi all,
called the bank call center no[protected] for inquiring on a strange debit of rs1.35p as OUD-D showing on my mini statement from my corp savings accounts,the first,second and third rep put me thru the ivr 3 times saying you need to validate your pin. I tried the atm pin as suggested..i asked the fourth rep what is the procedure to validate the same thru the sys...he was unable to explain...I still want my answer and does validating a freaky 4digit pn into a machine verify me? Isnt there a procedure to verify security details any other way...HDFC Bnk this is how you treat corp account holders???or are the big banks deaf for hearing consumers?or are the banks only wanting consumers to deposit hard earned money into their asses-so they turn into large so called global bank conglomerates???
