Battery *******

I took my car for service on the 13th of May2024. And on the 20th of May 2024 my car suddenly stopped showing that my battery low I kicked started the car and when got to work checked my battery only to realise my battery was changed. I am not sure why this was done but it’s unacceptable for me because it shows they hired *******. I took my car because I trusted them only for my battery to exchanged with a damaged one. Toyota Klipsruit is a place of *******.
