Battered by Ackermans during lockdown

Dear Sir/Madam My instalment with Ackermans, was R715, which I have been paying regularly until lockdown when my husband was not working. He is a Restaurant Manager. I phoned Ackermans that I can afford R350, which I have been paying without delay all these months. They send me almost ten (10) SMSs and phone calls a week. It got so bad, they even terrorized me when I told them I am with my work colleagues I got angry and sweared at them, now they just phone me to swear at me also. I would like advice to report them. Thanking you
