FRUAD AND HARRASMENT FROM LIFESTYLE LEGAL AND LOAN CHOICE SA

Lifestyle Legal and Loan choice SA has been harassing me for money owed for NO services rendered. I was one of the unfortunate people who went to Loan Choice to see if they can provide me with a loan. I did not complete all the forms sent but without reading the terms completely entered into a digital contract with Loan Choice. After I reversed the money they deducted of my bank account which I didn't even give them the details to, I have been handed over to Lifestyle legal. After which I got repeated emails and sms's for the outstanding amount, contract cancellation fees and with that extra fees every week. Where I had to pay R399 they summonsed me for R1400 after 2 months. I paid the money (duped into it as I was afraid of the legal implications) Now I am unable to get hold of the so called Lifestyle Legal. The phone rings, a voice prompt comes up and after a few minutes of holding the call gets cut off. I have been trying for 2 days. I phoned loan choice and they demand my ID number which I REFUSE to give as I do not trust them with my details, and do not want any more illegal transactions on my bank account they cannot provide me with said legal firms contact details, they wont allow me to speak to management 'as management does not take calls' and they insist on my personal details!!!!!!!! How can I give them my ID number knowing that they will be able to access my personal details and then once again try and deduct money for some other reason?????? And why am I unable to get hold of Lifestyle Legal. I sent the POP to them 3days ago and I am still receiving threatening messages stating that they are going to black list me. This is extortion and fraud at its best!!!!!!!!!!!!! Can anybody give me some advise as to what is my next step and what to do. I am getting the sense that Lifestyle Legal doesn't even exist and they are a front to steal money from clients that doesn't know better
