I sent this mail:
Hello Sir/Madam,
Firstly, I am very appreciated for being one of the winner for green card lottery and I was very excited. Because of my excitement, l noticed I made wrongly a format error (month/day, day/ month) while I was logging in my birth date to the DS-260 form also I entered my surname wrong by mistakenly because I have two surnames. Since I made these mistakes more than once I got error ''The Case Number entered is currently unavailable. Please try again later or contact the Kentucky Consular Center (KCC) by email ) or by phone (Public Inquiry Phone Number 606 -526-7500 7:30 am to 4:00 pm EDT Monday - Friday) for further assistance.'' I cannot login to fill in the Ds-260 form. Could you help me please?
KCC answers that:
Thank you for your inquiry.
Your answers on the DS-260 application should be as accurate as possible in order to minimize the potential for confusion and delay in your case. Once submitted, a DS-260 cannot be deleted or removed. If there is an error in your DS-260 application form or if you need to make changes, the Kentucky Consular Center (KCC) can unlock the form for you so that you can make any changes required. If you would like us to unlock one or more forms in your case, please reply to this address, including your case number, date of birth (MMDDYYYY) and the names of the applicants whose forms you would like us to unlock, and an explanation as to why you need the DS-260 unlocked.
Once unlocked, if you would like for KCC to process your application, you must resubmit it. A DS-260 will not continue processing unless it is re-submitted. Unlocking an application is the only way to make changes, or to prevent a form from being processed.
In order for the Kentucky Consular Center to assist with inquiries regarding a specific Diversity Visa (DV) case, you must provide the Principal Applicant's full name, complete case number, and date of birth in the following format (MMDDYYYY) as entered on the original entry. Please remember that the Kentucky Consular Center does not have the authority to tell you whether or not your specific case will be disqualified. Only a consular officer can do that at the time of your visa interview. Do not send any paper documents to the Kentucky Consular Center.
