I am tired of all of social media I've been on Instagram and I get an Indian dated with people trying to scam money out of me every time I try to go for help and Instagram or Facebook all I get is a bunch of forms that never finish either what I want to say is not there or it won't go through over and over and over again I have this problem I would like to delete all of my accounts. And when I get to that spot where they want me to put my password and they say the password is no good when I just changed it a few days ago. Apparently I got a moveable Facebook and regular Facebook and I can never figure out the difference or which passwords which but my phone won't keep it straight I can't keep it straight you can never talk to a person or even email one please help me and don't if you just give me instructions it won't work because I tried it before
