Coaxed into debt

On the 30.11.2015 I attempted to check online for assistance with a consolidation loan to help with my existing debt. I came across Loan detector SA and was happy with the service they promoted online, I did not know that later I will be billed on a monthly basis and they already debited R100 from my bank account. I'm unemployed and the money they debited from my bank account was the last money I have, which left me even more broke and under immense stress, I was also treated for depression thereafter and a month and a half later I received an email to say I owe them a bill of R1120.00, I nearly got a heart attack. When I app**** everything was done online and all requested signed documents, I have not sent. I was sent a congratulatory email and a ref no. LDSA *** and on the email it said I purchased a service pack. 7th Jan. 2016 I received a statement of account and I rep**** furiously, the last email I received was 9th Feb.2016. I feel I have been ********** and ****med and I won't pay a cent. I want my money back, because Loan Detector SA has done nothing for me but cause me more debt.
