Do stuff without your approval

They phone me yesterday (13/01/2020) about debt review then they sent me the documents I told them I'm not interested they said they will cancel it, now (14/01/2020) they phone me again and tell me about the portfolio I told them I said that I'm not interested then the guy told me it is already created , I told them how because I didn't sign the papers then he drop the call. What must I do now because I don't want to go under debt review
