Defamation of character!!!

I sent the below message on Sunday to your Facebook profile, was told the complaint was going to be investigated, requested my contact number and then.... nothing!!!

To say I am utterly disgusted in your staff at your MRP Home store in Bayside Mall is an understatement.

I was treated like a ******** and embarrassed infront of the whole store and customers becuse the surname on my store card and my ID don't match but the names are exactly the same. Even after I showed the account details on my app which again proved that its my account she was still not happy and made it out to be that I was trying to make a purchase on an account that's not mine!!! I even said I can show the proof on my banking app that I make the payments for that card number, I didnt have to offer that but was trying to think of everything else that I could show Nomvelo Makayi this is my account, and guess what, she wanted me to show her that, personal details shes not prive to.

This is unacceptable I want an apology from her, the store and you people and compensation for the embarrassment I suffered by being treated like a ********. If this is not done my lawyer will be acting against this person and your company for defamation of my character!!!
