My Sister has been trying to book an appointment for US Visa interview for over a week now without success.
When you click on the Calendar to select an available date, The Calendar screen pops up but it is blank with no dates. Then below you see "Submit" and "Cancel".

She has called them to report this several times and have also sent several mails. The respond and tell her it has been escalated and later that it has been fixed. She checks and it is still the same issue. We have tried with different browsers, different computers, different locations and even different time of the day with no luck.

I want to know if any other person is experiencing this issue?
