I really need help getting my account back

I would just like to know how I can get my Instagram account back, today I attempted to log into my Instagram account, @what_lucy_did, and I was told to log in on a computer, I then followed the steps of entering my details and attaching a photo graph of my I.D but I still have not received my account back. I am extremely irritated as I use Instagram to share photos and messages with a majority of people I can't reach anywhere else. I have a photograph of my I.D which clearly shows that I am old enough to have an Instagram account and that I am who I say I am. Sincerely Lucy Lauder
