Paytm Mobile Solutions — regarding merchant account

I have a complaint against paytm business. They linked my pan card and are now not delinking it. According to rbi guidelines kyc details can be linked and can also be delinked. When contacting them they give rough behaviour and don't help. They say pan is now linked. If a person with whom pan card is there receives death then also i think they will not remove it. If it not goes i will complaint national consumer court.
