Phone Harassment

I am being harassed by FNB Around the month of May I paid all my credit card fees and paid the credit card .

I missed this months payment which is R650

And I am being called every morning . The President put us on level 4 Lockdown plus I have been put off at work due to the Riots and looting how are they expecting me to pay when they can see in my Acc that I don’t have money no money is coming in . Can they stop harassing me the minute I get money I will pay n be up to date like I was
