msme scam calls

we get calls daily from this number 092281 71586, stating they're from Gujarat, helping fund MSME. Firstly, they do not have decency to speak with someone, secondly how did they get my number and details? he started speaking in Hindi and I answered him back in Telugu(not my mother tongue but just so that he knows how will he feel when someone speaks in a language that's not their native tongue). the nerve of him to say " India mei rehte tho Hindi mei bolo", and I told him " Aap Gujarat mei rehte ho tho mujse Gujarati mei baath karoge?" He kept on mocking me and then I asked what is it regarding. He says they fund MSME and just to tick them off I told I wanted to establish a Tea Shop, will they fund? I heard him avuse me and then cut the call
