Is it possible to get my old level back?!

I was at level 425, I updated my iPad and over night my candy crush automatically updated and I woke up and it was at 763! I have never gone that high lol but my mom has, she uses my wifi and is a big fan of candy crush, somehow my account is connected with hers how do I fix this. I followed all steps sent to me through email it didn't work I want my old level back. A very disappointed candy crush fan
