Micromax Informatics — your service center are cheating

Address: Mangalore, 575003

I had buyed online mobile from flipkart, micromax bharat 5 pro with 1 year warranty,
In my mobile on unlocking a particular place in display its clicks automatically and any folder or file on that place opens so i visited the 2 micromax service center in mangalore they told that its a hardware problem and we do only paid service so after searching i found one micromax service center which repairs warranty mobile so i submitted mobile there after 3 days i called them because of no reply from them, now they are telling due to moisture the issue is there. Its due to rainy season
But i am not convinced because there is no chance of getting moisture because i use that mobile at my home not even get out of my home and no water even touched it. So they are just cheating me by telling moisture issue
