Zero customer service!!!!

We went to Sterns in Mall of Africa on Saturday, 20 March 2021. The lady at the till was unbelievably rude and in professional to the highest degree!!! Ny husband was trying to explain to her what we need done with two of my rings (both previously bought at Sterns) and this lady just kept on interrupting my husband and asking him if he bought these rings at Sterns. She then interrupted him mid sentence because she wanted to hold the rings in her hands. To top it off, another man walked into the store (he works somewhere in Mall of Africa) and whilst we are busy engaging with this lady she turns her attention to him. He greets her by saying "hello beautiful" and this lady starts flirting with this man and telling him how she hasn't seen him in such a long time right in front of us!!!!! Where the hell is a customer service????!!!!! Its ok to flirt with other employees in front of customers???!!!!!
