He was roleplaying and this person asked him if he wanted robux and he said "yes of course but I have to ask my sister first this is her account" and the person said "surprise her with the robux don't ask her tell her at *:**am or later. So the person asked for MY facebook account and he gave it to them and they were chatting and gave the person my password to my email and account. I found out because I went to play with my best friend and I want to log in and it said "incorrect password or username (Now I only se one password for all of my games and stuff even my email) so I went to forget password and I put in my email and the recovery email wasn't my mothers she (at the time I got the email when I was * and now I'm ** *** and my phone broke and stuff and I didn't have my phone) and my mother told me to contact you so you could get me my account because I worked to get my robux cards and now I have to work all over again so please, please, please get me my account back. the user name it cupcake******.
