What is the latest time Uni can make their offer?

I know Uni decision deadline for the Uni are 17th july

But what is the deadline time?
Is it midnight or..?

I can't becus their number goes to India

Which university is it?

I just rang their UK number and she was unable to put me through to the number because that department is busy an do not want to take my call and the lady i was speaking to gave me another number which is the india admissions team number

I phone the admissions team in india and they said my application is still under referred
but i wanted to speak to someone in UK

I take it i have been rejected
but it doesnt make sense because i had my interview 2 days ago

Can you find the direct UK number for either the admissions team or the international office at your university - either should be able to find out what is happening and get things sorted to avoid you being rejected by UCAS because the uni were too slow.
