Unused Membership

My entire family has been members of planet fitness for some time now, we all (5) got covid 19 and my father did not make it. he was the one paying for our memberships. We contacted Planet Fitness explaining due to us ALL being in the hospital we are not allowed to exercise for 6 months and without my dad's income we will not be able too pay for a membership that we would not be using. They have been calling me non-stop every single day for 3 months and making treats, The last person to call me 05/10/2021 (12:13 PM) was so extremely rude when I tried to explain the situation to her, she is not even calling from planet Fitness but a debt collection company. How is this justified? i have received sms's stating that I will be listed on ITC again more treats.
