Continued harassment for a contract that expired 2 years ago

The continued harassment from these people is really getting insane. It has been more than a year now maybe two since my contract expired with these people and up till to day they are emailing and text messaging me with these types of messages, "LAST CHANCE TO SAVE BIG! SETTLE YOUR ZONE FITNESS ACCOUNT BEFORE 28 FEB 2020, AND GET A 30% DISCOUNT OR RISK NEGATIVE CREDIT RATING AT THE ATTORNEYS REGARDS, *** , ***"
