FaceTime missing from settings & restrictions

I have an iPhone 4s, my mum bought it for me from Tbilisi, Georgia along with her own.
She has FaceTime on her phone but I do not. It's not in settings anywhere, I've checked iCloud too and restrictions but restrictions is off and FaceTime doesn't even show in there either.

I know that Apple have to remove certain things including FaceTime in certain countries in order for the countries to sell them, but Georgia isn't one of them.

Please help
