Closed account, Now reopened and handed over to Landau attorneys

My name is Thapelo Mokoena, I am highly irritated and disappointed by planet fitness, I received a confirmation email from planet fitness that my my initial contract was closed in 2017, I re-opened a new account in 2020 and all of a sudden I owe them and I'm getting calls from Landau attorneys.. What a **** UP by planet fitness
