Getting random sms security codes, not sure if under attack?

[FlashSA]

I've received 2x 6 digit verification codes via sms from +27820070120 this evening. In my phone I see I have received 5 verification codes previously over the last 6 months which would have been legit and this leads me to believe a service I use is under attack.

Anybody have any sms verification codes from this sender and are able to recall what service it relates to? It's not Google/Gmail as theirs start with G-

The text of the sms is: Your security code is: xxxxxx
