Instagram Phishing Took Over My Account and Exposed My Private Information

Not long ago, someone hacked my Instagram account after I got a weird fake complaint. I got a message that seemed like a real complaint on Şikayetvar, but it had a fake naked image alongside my photo. I got a message that made me click a link to find out who reported it, and sadly, I ended up entering my account info without noticing it was a phishing. My account got changed from private to public, and now I can't get into it. I’m really worried about my private info being out there and I need Instagram’s help to get my account back as soon as possible. I don’t want to have to start fresh with someone new; I just want to get my privacy back.
