My wife has two accounts in sahara b. Money bearing no's.[protected] and [protected]. She is not getting monthly interests since the month of october 2018 and facing tremendous harassment from your bansdroni branch, kolkata (Contact no.- [protected]).
Being a senior citizen, i physically visited bansdroni branch five to six times but till today my wife has not received monthly interests or any favourable response from bansdroni branch.
Kindly make an arrangement for the payment of monthly interest as per terms and conditions of the scheme or payback the principal amount in full i[censored]nable to pay the monthly interest.
