Plabet Fitness the worst!

Planet Fitness is the worst!...I cancelled my 2 year memebership in 2016, paid the settlement and everything. I signed a 6 month contract in August 2018 and cancelled it in Octobet. I get a call today being asked to pay R3 336.88 to settle my account. They've been billing me from 2016. They never get back to you about your enquiries but they are quick to call to tell you about your debt.
