Instagram account temporarily locked

Hello,

my instagram account has been locked, i dont know why its been locked but i really need it back, this is an old account and i cant remember what email this is so i cant get the security code, is there any way to know what email is linked to my account because half of it is written with asteriks hiding whats written, or a way to contact instagram? ive emailed them about 4 times and they havent even gave me a response.
