Dissatisfied potential client

Stopped working out due to financial challenges and i think also covid. This was in 2019 or 2020. Tried to rejoin gym recently and I'm told I need to pay 50% of R4000 for services that were never rendered. Thought VA is a service provider. You pay and you get access to the gym. Now they act like credit providers. The debt doesn't even get prescribed. You owe them for life.....this company is a joke.
