Worse, horrible customer service ever,

I have a personal loan with Nedbank, I company has been closed since March 2020 due to COVID-19 which I have been communicating with them, some months they debited me some not, our company only opened first week December meaning I was gonna get half of my salary, they sent me an SMS stating that they will start debuting again on the 18th December which was fine with me, however to my surprise they debited me twice and it is the entire salary I got from my company, now I do not have money for transportation to work, pay rent, buy food for my family, not to mention clothes for my kids. They did this without even Informing me that they will debit twice, how can they be so inhumane like this, I'm stressed out, thinking of taking my life also, I acknowledge my debt to them, but to be left without a cent and worse part its festive season where other people are enjoying with their families, as for me, I'll be busy staying at home, as transportation money gone, food money gone, I dont even know what to tell the landlord as she is aware that we are back at work and expecting rent, if they would have taken only for one month I would have been fine, now I called the bank but could not get assistance all I am told is that I have not been paying for a while, but I made some arrangements with them, I even claimed on my insurance which they have not given me any feedback since all I get is excuses that they have so many people applying there is a delay since may I have app**** but no luck, I also wonder as to why does one has to pay for insurance but can't claim in case of this unforeseen event. I hope I will be able to see tomorrow, but with alot of questions, what am I gonna eat tomorrow, what will I tell them at work, will they understand,?.???
