Payment for a lockdown

So i joined the gym last year at zone fitness muizenberg i got a phone from sasha telling me I'm in arrears i must come pay in at the gym so i asked her how many months i have left for the gym to my understanding I have only 4 months left .Anyway she told me i have 7 months left and i told that cannot be she said i must pay until March because the gym was closed during lockdown and I'm like " really now" I told her that was not fair because no one saw covid-19 rocking up in SA and why must i pay for all the months the gym was closed and she said that i have to pay thats what the contract says.

I dont see why i must pay those extra months because off covid-19 thats not fair people that was home during the lockdown and to draw UIF so whats it with zone fitness they busy here with ****************
