Unexplained enquiry on Credit profile

I received a message on the 24th of December 2020 that a credit enquiry has been done on my credit profile, and guess who was the culprit Capitec bank. I didn't even app**** for any credit, the only thing I did on the 23rd of December was load your capitec bank on my new phone at the Garden Route mall branch in George. The reason why I am so upset is because my credit score has dropped. Please explain why your do something stupid like that
