Absa credit card

I have been a customer for more than 20 years. 2 years ago I became unemployed, dispite this I continued to keep up with payments to my credit card. My husband works in the building trade so work was scarce for him too. When covid happened both of us were witout invome and Absa offered the relief payment plan. That help a lot as we have had zero income since lockdown started. Daily living has been an absolute struggle. 2 weeks ago I received an sms stating my payment relief will be coming to an end but I can make another arrangement by choosing the options. I advised yet again that I am still unemployed with zeto income. Today I received an sms asking that that full outstanding payment be done. They have also added on interest for the period we were in lockdown so now I owe an additional 10k which is just interest. I am not sure how I am supposed to pay this money when I have no income. Absa offered help but then dont respond...shocking service for someone who has been a long time customer.
