I reached out to IG support team several times over the course of past 4 months through (my account was hacked form) but they failed to acknowledge the issue and just suggested that I change my password and use a more secure password.

Even though their support <a href="https://help.instagram.com/149494825257596?helpref=search&sr=2&query=hacked%20username">article</a> clearly mentions that you can use the (mentioned) steps to report if your username/email was changed in the process.

Would appreciate any help, on how to contact IG support team to get the issue solved. Thanks.
