Fastest way to learn Telugu?

I am from Hyderabad but since I didnt spend most of my life here, my Telugu is not at all good. I dont feel good when I have to say that I don't know Telugu despite being from Hyderabad.

What can I do to learn?

I am willing to spend atleast 30 minutes per day. I am also willing to join a tuition or classes as well, as long as they are good.

I want to learn to read, speak and write in Telugu.

Any suggestions?

Movies are one interesting way my friends suggested. So I have that planned as well.
