You can only do research with data can you can obtain. What you want sounds difficult to get and you don't want your work to fail just because you couldn't get data.
Though have you tried talking with multi-national companies that have Indian divisions. If the HR in India will listen to you, they might help you get data from another division in the same company. Also to get companies to help you have to explain to them how you are helping them. Just asking for help is difficult but if you are selling them some useful data in return for access, that is easier to sell.
Also privacy laws in Europe will be very strict about this, so I doubt any European company will share any data.
