Income Tax Department — black money and tax evasion

Address:

Sangrur, Punjab, 148001

India cloth house in city sangrur punjab state holds alot of black money they usually take cash from their customers and if someone is willing to pay by card they rarely accepts the card and they don not even give the original bill. They have upgraded their shop in a 3 storey building. They do not pay the required taxes according to their income. They always cheat people selling a piece of worth 1000 in 3000. A lot of people have complaints against them. Some days ago a person tried to show their black money to people on social media but they did something and they have strong political support system due to which that person had to apologise. I think this is the only system in india that people are keeping black money converting them in white n if someone speaks up they shut them down. I want officials to look into this matter.
