I need help urgently Debt Busters is stressing me

I've been with Debt Busters for 5 years now. I was told towards the end of last year that I'll be finishing up my loan repayments/debts on July this year(2024). I am paying R3874 and I was told that my last installment in July this year would be R2700. I did contact them earlier this year to confirm what they've said last year and yes the story was still the same but to my surprise when I've contacted them earlier this month apparently I'll be finishing off paying my debt in December and when I've asked the reason they've told me that I'm behind with payments with 3 stores and when I've asked them as to why am I behind hence they deduct the money every month their explanation was mumbled and they asked if I wanted to dispute that I've told them definitely I am disputing that and I was told that the matter will be escalated to the top management and that I'll be contacted till today no one has contacted me. Numerous times in July when I've asked for the reference for the calls I was told that the reference number is too long they will send it via sms but they never did so every time I make a phone call I have to start my story from the beginning. There's an email that they've sent in July telling me that I've settled Ackermas and they are waiting for the settlement letter that has already been sent to them once it arrived they'll send it to me but when I'd reminded them there was no reply. They also told me that there was a mistake from Old Mutual apparently Old Mutual has sent them the incorrect balance but till today they haven't gotten back to me. What they just did they just deduct the R3874 that they usually deduct. I have told them that this is stressful and I can't sleep at night and I've asked them why they say I would get a financial freedom whereas they've given me more financial stress. Please Hello Peter kindly assist I can't take this anymore I am so frustrated.
