That's what I wound up doing when it got really bad. I found the easiest way I could complain (I think a web form at the time) and sent them all the details each time.

Any results?

Oh yes! To be fair, they were really bad at the time, like 3~10 a day for a couple of months, I didn't have much choice to complain. It stopped within a week. Now, I think the only weirdness was around new years with the Android wrong-person text bug (whatever that was). My work phone I get maybe 2~3 per month, if that, but I don't even know who to gripe to on that one except resources at work, but it isn't so bad I don't mind so much.
