Facebook Meta Social Media Specialist - Lost insta account

My Instagram account of 25K followers was recently de-activated on Instagram. We hadn't done anything differently to eat we've done for the past 8 years and we've never been able to speak to a human. We had a message saying we have violated community guidelines and asked to send a head and shoulders photo with a 6 digit code. We were told we'd be contacted after the review. We heard nothing more. We have a business account number and our instagram is attached to our facebook account which is still live however we have started a new instagram account (same name with a 2 on the end) so now, although we can see our old account sat there, if we try to talk to anyone at insta they only recognise the new account.

We are looking for someone who knows Meta Business backwards and has dealt with this sort of thing before.
