Rude cashier or whatever she is

Good Evening,I am from Welkom,And today I went antook the car for test and was helped by a lady Called Tsoho. Then took the car for neccesary tests and it failed and had to go and sort out the issues with the car then come back after frustrating day I had and went to one lady who helped me with payment and then asked me to go back to and Tsoho who was very rude from the word go for no reason and roughly told me I can’t get the disc due to my outstanding balance with my other vehicle,I told her I dnt have another vehicle built she rep**** rudely and told me that I have another vehicle,I asked her how and which one as my previous car I sold it 4 yrs ago.....she started screaming across the counters and speaking to other colleagues that I’m a liver that she didn’t help me in the morning and I gently asked her why she it yelling she ignored me and that’s when I asked for manager and they told me they’ll deal with her as they have received many complaints of her attitude bt what are they doing about it
