Daily light thievery

In August 2020, I was retrenched and contacted African bank as I had a loan with them. I was advised to provide all relevant documents in order for Credit Life to pay. They did pay however a whole year later I'm being called and told that the account is still active. I am being called daily by them requesting payment mind you I am still unemployed. Please tell me how an unemployed person with practically no air in her stomach is supposed to pay for a loan that was partially settled.
