Address: New Delhi, Delhi, 110485032

Dear kotak team,
A/c no. [protected].
Please convert my salary account to savings account with 0 balance.
I no longer work in mystique logistics pvt ltd. I'm getting continuous mails & sms regarding some service charges. Would appreciate if your team could check on this.
Please convert from salary account to saving account, will i get my last deducted amount 1180 for salary account? If yes please tell after how many day's to convert my salary account to savings account with 0 balance. Also confirm will receive the debited amount 1180 rs yes or not.

Thanks & regards
