I have Gotten WHITE LTF on my Kotak 811 Account . The screenshot you shown of consent was given to me as well .
The truth is that the customer care doesn't see LTF status of any Card . I had also called them and asked them casually one day , is my WHITE LTF or not ? They said no sir , it is not...
I have got Kotak White LTF with 811 account . So , dont think .. Account is an issue .
@soumendunanda you just have to close FD card now . Wait for 6m and you will get pre-approved offer after that ... Just keep using your 811 Account to the fullest !
