I subscribed to Pinterest but now I wish to unsubscribe. I tried logging into my account, I think, and a bunch of checkboxes popped up on the screen. I clicked on them because they were asking me to pick options for how i want to unsubscribe from Pinterest. I tried to unsubscribe by finding a button that would help me save my settings, but I did not find one. I therefore exited out of Pinterest and now, i am still recieving these emails. I am no longer interested in recieving emails or having any involvement with Pinterest. Any assistance with helping me unsubscribe will be appreciated. I cannot do it myself, as the sentences above explain my issues with the website. Therefore, I am requesting that one of you contact me and assist me with the unsubscribing, or that you unsubscribe for me. Please note that I am unwilling to share my private information, i.e., password, username, etc.
