Need Suggestion

A few years ago, I created my profile on the TCS iBegin portal. Unfortunately, I entered an incorrect date of birth—the year is wrong. Later, I emailed TCS requesting a correction because this field is disabled and I’m unable to update it myself, but I didn’t receive any response. I have now cleared the TCS interview, and I’m worried that this issue might create a problem during further processes. Could anyone please guide me on how to get this corrected?
