Harassment of payment during lockdown when I dont receive a salary

I keep on getting calls from Daly Credit corporation where they ask me when will I make payment toward my foschini account (trust me I really wish I could get this off of my name) they keep on calling me, so I need to pay my outstanding balance and their phone calls. Yesterday I got called by a lady and I said to her how do you expect me to pay if I dont get a salary. I can only start working on level 1 after lockdown. She just half heartedly answered me and put the phone down. This morning, Shaun from daly corp calls me again I freak out and say why do you keep on calling me (this time they call from a cellphone nr 082 nr not their regular 066 nr or 087 nr). They call me everyday and ask me when I can make payment, and I keep on asking them stop calling me and freeze my account or what ever Ill pay you as soon as I can work. How is this harassment possible and continues! We are already so stressed financially now I keep on being harassed by Daly Credit Corp!!!
