I forgot my Snapchat password, I didn't enter e-mail and phone number, how can I get my account back?

My account is locked and when I want to open it, it asks for a password, but I forgot the password. I requested help from the snapchat help service, but they always send the same and it doesn't work. What can I do? How can I get it? I can't remember the password. Please help.
