I know this comes down to institutional incompetency, but at some point there was a singular human person putting the template content the SMS message in question was generated from into some computer system somewhere and I genuinely wonder what was going on in their head that made them string the words together in this way. You'd have to give it a true, earnest shot to make it worse.
"Incompetency" is an interesting word.
The old maxim about incompetence versus malice suggests a binary choice.
I prefer the more nuanced take that there is a spectrum of positions between the two, and other dimensions that describe a cluster of intents, both conscious and unconscious.
Take the UK Post Office scandal where we see incompetence layered on top of malice, layered on top on incompetence. In some organisations obviously deliberately harmful positions are written into "policy". Often this comes under "PR" [fn:1]. More and more "AI" will be used to disguise malintent and deflect scrutiny.
In the final episode of the ITV dramatisation [0], Alan Bates (played by Toby Jones) delivers an absolutely shocking, knock down line. When talking about incompetence and evil he says: "They're the same thing" At some point there is no difference between incompetence and evil. For a deeper psychological discussion of that listen here [1].

[fn:1] Edward Bernays seminal definition of public relations outlines a creed of deception, manipulation and disinformation which is antithetical to security [2].
