Very angry customer

They called me to help me with my debt, they said they will help me reduce my monthly payment. At the time I was paying around R2400 a month and only had 3 months left to make the payment and would be done. They told me they will reduce the payment to just R1969, 32 a month which I was happy with as it was a reduction, they told me I'd pay it for the next 3 months so I agreed. Bear in mind all this time the person I'm speaking to has told me they putting me under debt review, he sends me a debt order to accept via my app to agree to the direct debt. I accepted the debit order set up. He then asked me to send him my 3 months bank statement which I did via what's up and he confirmed his received them. He then goes to reading his terms and conditions and then tells me his putting me under debt review and I said hawu, why didn't you tell me at the beginning that that's what I was consenting to then to only tell me at the end but then I said continue it's okay but felt like I don't feel like I was given the choice to really decide on the matter as the debit order had already been set. So I let it like that. They sent me their contact details to contact them via what's up. The next they I what's up the number given and I said Hi, the person responded "Good morning, how can I assist?" I then said "I wanted to know how do I cancel our arrangement" the person read my message and didn't respond anymore. I then sent a question mark this was in October when I signed up to this and they only responded back to me 13 January 2025 by send me a number to now contact about this. Bearing in mind doing this know it would be to late for me to cancel the agreement we did. I then later found about that I had limited time to cancel this arrangement which I did try via what's up and I have proof of the conversation via what's up. They are now charging me the 4th month now which is not what the person told me over the phone and had I known it would cost me more then three months I wouldn't have don't it cause it wouldn't make sense at all to end up paying way more then I truelly owed. I have logged a complaint but I've sent to receive a respons from them
