Anybody else got a wrong iCloud purchase message from maxis with some random number even though you don’t have that number as supplementary line ?

What is wrong with maxis lately ?? Previously my cousin signed up for fibre but because I had complaint about cell service at that location before I automatically got all the messages for the fibre installation and the installation guy even called me instead of them for appointment. I have nothing to do with their account but still got called and SMSed by them non stop.


What kind of data security are they having in maxis to allow this kind of data leakage or false data placement
