Hi Archana,
While I understand your desire for an OEM screen, there are a lot of good aftermarket screens available out there. One thing to be aware of is the fact that your phone originally came with an AMOLED screen which is generally a very good quality screen, but there are aftermarket sellers pitching LCD versions of your screen that will be much cheaper but of much lower quality. Did you get one of those by any chance rather than an OLED version like the original?
I've dealt with a lot of aftermarket screens and the OLED ones I've bought have pretty much always been comparable in quality to the originals.
Just food for thought; I certainly don't fault you for wanting a screen that's guaranteed to be at least as good as the original.
You might try Mobile Sentrix; they sell screens that are labelled as Refurbished.
