Debt help put me under debt review without my consent

Debt help put me under debt review without my consent . the was a guy by the name of William that call me and he never explain any implication he just came about telling me that I'm being over charged by my creditors and so forth then we ended up having a misunderstand when he wanted me to sign a document which i did not sign via a link that was sent on my phone . then two weeks later i'm receiving emails from my Bank about my Certificate of Balance being request. this is so wrong
