Woolworths

Good evening,
I use this petrol station daily with no problems, however, today I went at an earlier time of day than usual (around 4:00PM) and had an issue with the Manager, who gave me his name as Puntik (unsure of spelling).
As I went to fill up my petrol, he told me to come inside over the microphone. When I walked into the store he immediately started YELLING at me to pre-pay for my petrol as he believed my car was unregistered (it isn't). He began to swear at me when I defended myself, telling me to "f*** off, f*** off and get out". When I asked for his name, he refused several times before giving me his details.
I'd like this matter to be investigated as soon as possible. It was extremely unprofessional, rude and aggressive.
Thank you in advance.
Hasan
