Credit assurance

I'm struggling with Woolworths since End March 2020 with no Reply from them, send over 20 messages, e-mails and platforms and also try calling but the numbers don't work or is not answerd. Now I'm given over to dept recovery and they give me a bull story that after 10years of bean a client I don't have cover beacause I made arrangements for 2 months to pay R200 less on my installment and now 4 months later I'm informed that I can't use my Credit assurance because of special payment arrangements and let me state that I paid more than 80% on my installment. This is Unacceptable that you answer me almost 3 months later if I was helped in March You could asist me with my credit assurance that i asked because of Retrenchment. Woolworths for the people in crisis Yes write.
