I have clarified same issue with tininfo@nsdl.co.in. There is no such provision to cancel the acknowledgment or application which is already generated. You are requested to ignore the Acknowledgement (if not submitted to bank) which is generated with invalid details and upload the new Form 15CA with correct details.

Hi Friends, I am also facing the same problem and need to revise the Form 15CA already filed but not been given to Bank as the amount of TDS has wrongly been entered.
Could you please forward me the copy of mail received from tininfo to my mail id a_khandelwal@bchindia.com

Any form 15ca is valid only if the respective payment is reflected in the bank account. As on date there is no procedure to revise incorrect 15ca, hence would suggest to just ignore the same and re upload afresh.
