Paytm — Unwanted Service and Notifications

I am receiving payment and credit notifications from PayTM - a service I do not want and have never activated. I do not know how they got my information. I received notes everyday beginning April 7. I have emailed to request immediate stop of all activity and removal from all databases. Please advise steps I can take to end this connection with PayTM and what process I follow to lodge a complaint.
