Bad customer service...

I fell unemployed in 2020 so i couldn't pay my subscription . So i made a payment arrangement and paid up the account... but could not cancel because their system said i must wait 30 days .. so after it finally got canceled.. they send me an sms saying I own them R1500 .. even though they said its settled on a recorded call... i have been asking them to call me so that this can be settled but not one calls .. i don't know if they are scared to talk to me or they know they are in wrong ... they just send me smss saying i must pay R1500 ..
