Hi,
I got three transactions sms on 4th january 2020 around 4:01pm to 4:05 pm, total amount deducted as 10000, 10000, 3500 that is 23500 inr. Immidiatedly i reported to citibank and dispute id raised d[protected] for first transactions and for other 2 transactions i did not received any dispute id and bank gave provisional credit of 23500 inr, blocked my card, new card issued.
On second day, i got sms alert that some one is tried to withdraw from atm at bihar, jharkhand etc. I reported that to citibank but citibank told me to ignore the alert as card is blocked.
I sent the police complaint and card copy on email citialert. [protected]@citicorp.com, then i got call from citi and confirmed that transactions done from bihar location are not done by me and told me to share the card copy on email.
I shared that too on citialert. [protected]@citicorp.com but after 50 days i got call from citi and said that investigation is on hold due to not received any card copy and sent me the dox retail. Dox. [protected]@citi.com.
I shared the complaint and card image on retail. Dox. [protected]@citi.com,
After that i got sms regarding above dispute id is not elligible for reversal.
I am worried about using citibank debit card as no cooperation from citibank for the incident happened with me.in fact citibank customer care executives are saying go to police.
Police are saying got to bank.
I am confused what is next, i lost my 23500 rupees with atm fraud and citi is not taking responsibilty. : (
