Suspicious texts

[Percy7]

I have been receiving AirBnB texts to my phone with “security code” and a number.  There is no reason I can think of - I’ve made no contact or even checked my account to prompt this happening. 
I asked AirBnB but NO REPLY. 

Does anyone know what this is all about- why is it happening?

WHY WONT ABNB ANSWER ME?

It's a bug, a known issue, been happening for weeks and mentioned on this forum dozens of times.  Ignore it.
