I've had straight talk for about 6 month and last night they assigned my number and whole account to someone else. My service became invalid and everything on my account was now available to another person including name, address, date of birth, security pin AND the answer to my security question! I also gained access to their same info trying to fix it. I spoke with so many people over hours on the phone. A "manager" said all he can do is update my info, proceeds to send me an email to my correct email address, with the other guy's info it it that my service went to! Wtf. I screenshotted all of it for evidence.
