Forced payments

Good day,

I had a call from African Debt Advisors claiming that they can assist me in reducing my debits by 60% then I was interested and gave them my information and authority to get into my profile. They notified all the companies that i owe and i asked them to send me the documents that i need to sign. When i read the documents i have noticed that the is so much than i am binding myself to and they will not really be assisting me other than ripping me off. Then i told them that i am not going to sign that and i am not interested. So they must reinstate all the notifications that they have sent to my debts companies and they said i must pay R2700.00 for cancellation fee and if i don't do that then they won't be assisting me. They are so rude and unprofessional. Any advice on what i should do?

Regards, Vuyo
