My phone isn't sending texts to one person.
I have a gophone, and it suddenly decided to not send texts to just one person in particular. I even went out and got another gophone to see if that fixed it, but that didn't work. My texts all show as sent, but she isn't receiving them. I can receive them from her just fine.
I tried to find an email or live chat to contact an AT&T employee, but apparently it doesn't exist because every link i clicked just sent me around in circles. It's a little ridiculous.
