Hi there, @Mansoor_Ahmad 
We have a Google Reviews widget that should work great for your case. The new reviews appear automatically there, but not right away.
The thing is that our widget uses a cache system to make everything load faster and reduce the server load. So the reviews are updated every 72 hours.
Feel free to test it out and let me know if it works for you
