I got an AT&T Z432 in April, and have not had any other phone before. It was working fine (with a few quirks but nothing too bad) when on Saturday, I was texting one of my friends and he mentioned that he'd been trying to get a hold of me for the past twenty minutes. I got none of his texts other than that one.
Yesterday, it spread to all of my contacts--I'm not getting any texts from anyone, even though I can send them. I've tried everything in the Ting troubleshooting article, in the AT&T troubleshooting article, and NOTHING WORKS.
I tried to get a hold of Ting customer support but waited for nearly 15 minutes on hold before giving up.
