The "bad month" error message on tgeapcet.nic.in suggests a technical issue with the counselling website.

There might be a temporary glitch with the website. Give it some time (a few hours) and try logging in again to check if the slot booking option is available.

Sometimes, outdated cache or cookies can cause website display issues. Try clearing your browser's cache and cookies, then log in again to the EAMCET counselling portal.

If the issue persists, try accessing the EAMCET counselling website from a different device (computer, phone) or browser to see if the error persists.

Verify with your bank statement that the payment has indeed been debited for the counselling registration fee.

If the payment shows as successful, take a screenshot of your bank statement (showing the deduction) for your records. This might be helpful in case you need to contact the EAMCET authorities again.
