What were the reasons for refusal and error in law? Raise a webform. Using a representative doesn’t guarantee approval. Or did you lie and say you did it yourself?
Post reasons for refusal. So you didn’t have anyone help you do the application or pay the consultant? Raise a webform and tell them you didn’t get any help.
Okay then if that is only reason for refusal then submit webform asking for reconsideration. There are no timelines for reconsideration so you may not find out for weeks if file is even reopened.
