Address:

Anand, Gujarat, 388001

I having central bank of India (cbi) anand. atm debit card, on 18/01/2017 from cosmos bank at i swiped as cbi atm was closed, so on swiping in cosmos atm it started slowly processing & after few minutes i received message in my ( rmn) mobile for debit of rs.3000/ at 11:49 am & few minutes machine not dispensed amount & displayed message of transaction is cancelled & slip not come out. SO i immediately approached to my cbi manager &informed the matter & i asked him i want to complain it, he replied that it is not necessary it will be reversed with in two to three days. After few days i again gone my bank & informed that still i not received reversal of debit amount so they tell me to give complain in written format so i filled format & submitted on 24/01/2017, as of still today i am not receiving proper reply from bank for which i lost Rs.3000/ due to machine error. Hope you will find a solution asap. Regards
