How to report a lawyer if he is not communicating with me?

Dear Sir/Madam,

I had an accident and was diagnosed with a spine fracture.

A lawyer came to me, and I don't know where he got my number from. I needed to give him a power of attorney (POA) while I was on my sick bed, because he said he could not proceed with my case without it.

Fast forward, a judgment was passed in my favor, but he never told me. He would never call me, and if I called or texted him for updates, he wouldn't reply. He later went for an appeal without my knowledge.

Now, the case has been in execution for the past two months, and he is still refusing to pick up my calls for updates or any information on my case.

He has not been transparent or fair with my case. I called their office line today, and the administrator said they have finished with my case, so the lawyer is supposed to do what is expected of him.

Please, which are the proper authorities to report this lawyer to?

He is really taking advantage of my patience and the POA in his hands.
