defamation of character

My little brother went to game stores Menlyn yesterday to purchase headsets for his phone and tested them in the store and found that they’re not working. He then went back to the shelf and took another box of which was working and was harassed by the store manager and the security telling him that he has to pay for both, without any hesitation he paid for both and asked if he can exchange the ones that are not working something else the store manager( Hendriek) refused and wrote on the one receipt non refundable as he claims that this is malicious damage to the store property and he was thrown in a holding cell for 4 hours, confiscated his belonging and was told he cant even inform his family of what was happening. A friend of his who contacted me to let me know what was happening was also thrown in the cell with for trying to help resolve this issue. When i got to the mall after i was informed by another of this I was told by another manager Nenad that they could home and that they’re welcome in the store at anytime. I then asked them to call the police and open an actual case against my brother and his friend and i was told that they cant do that coz the police would take too long to come there.

I am not happy about this we are regular customers at this store and this is the treatment we get!… this is defamation of character!…you cant treat people like this!…
