I received a call from them asking me if want them to help me with my clothing account since I am under debt review. I told them I will get back to them. So on Friday they debited r1500 out of my savings account without my concern which to me is *****. I have been trying to get a hold of them but their phone is not going through until a lady got back to me, telling me that they already started with my application which I did not ask for and she is rude. She said they are going to take 900 and give me r600. I want my r1500 cause I did not approve them to help me with my account
