I had one kotak811 account 6 years back. I wanted to get it closed, but they were not agreeing.
After 6 months, they started asking for full kyc, which I denied, as I wanted to close the account.
After 6 more months, I stopped getting any calls/messages and monthly statements. So, I assumed the account is now closed.
Now after 5 years, I applied for kotak Credit card and gave all documents. Now today I got a mail saying your mobile number is updated (my old number was changed by my current number) and last digits of crn mentioned was same as 811 account.
Is it possible that they reopened or never closed that account and now they completed kyc using credit card documents? How can I verify this? Also, how can I properly close it?
