How do I downgrade my Moto G XT 1033 from Lollipop 5.0.2 to Kit Kat 4.4.2 ?

[AC Question]

I am thoroughly disappointed with Lollipop 5.0.2 and prefer the older version of Kit Kat that the instrument was supplied with. This was purchased through an e- commerce site by name Flipkart in India, about a year ago
