Instagram hacked, what to do?

Question

Burglary protection

Guys! in general, it’s such a thing, who is an expert on hacking) they
hacked instagram 2 times in a row, they changed both the login, and the password, and the link to the mail (I have information about the mail), the photo left only a thousand subscribers accrued and a link to privat girl video posted, through the technical support service I restored, changed the password to 16-digit and mail binding to gmail, as a result they hacked the 3rd time and now everything has been demolished cleanly - there is no photo, no page, no my previous comments under other people's photos, as if I and was not registered)
the question is: how could they hack? and what to do to restore and take revenge) I
wrote to technical support until they answered ..
I will be glad to have any helpers in this matter)
thanks

We could get passwords via free Wi-Fi... And so simple passwords, trojans, viruses. The access paths are all standard...
