This is how the market economy works. Take any business for that matter. One company sells a good for x price and then comes a competitor and sells for less and tries to give better quality. So if you dont want that to happen then there should be only one company for everything in the country and they should all be run by the government.
Probably if you own a business however small it may be then you may have to shut down as there will always people who do the same business as you do and could not compete with you.
So are U willing to close your business the same way you are asking them to do.
Tomorrow bigger company will come and compete with Reliance. This is how it works.
If not then you are talking the same dirty Communism which will not survive anywhere.
