I registered a Google Account two months ago solely 1-888-653-7618 to use as my third Google Fi line, and the account was suspended for a "violation" of the rules of service. I never use the account or the email address; I just use them to sign into Google Fi.
Apparently, Google makes these types of mistakes, and it's really starting to irritate me. At the very least, tell me what "violation" you claim I committed, because it is impossible for me to have violated anything because I only use the account for Google Fi. The only one being violated here is myself.
