Cutting corners

I received a loan offer from discovery bank and I accepted and I tried to be a good customer, make payments before the due date even, and I have always paid more than the minimum amount, but at this point I can no longer make payments to Discovery bank, due to being financially strapped,, I have been under debt review since 2016, Discovery was not wven supposed to offer me a credit card under those conditions but I believe corners were cut somehow and it landed me in even deeper financial distress, therefore can my account be s****ped/written off, any required proof I can forward through, failure to do so I will approach the national consumer tribunal for litigation as this constitutes reckless lending.
