Appalling, aggressive, threatening customer servic

I have just returned from Camelot Service Station in Pretoria having filled my vehicle with fuel. I am extremely upset. Firstly they have 6/8 pumps. Only one of these pumps had fuel. I had to wait +/- 15 minutes to be served. Having filled my car I received an SMS from my bank (Investec) to say that the payment had been made. The attendant said they had not received payment. I asked for the manager to discuss with him. The manager walked upto my vehicle and said \ Pay your FU****G bill else I am getting the police". I was utterly shocked. He stormed off. An attendant asked me to move my vehicle to the parking area so that others could be served. I started my engine and moved forwards. The manager/owner jumped in front of vehicle screaming that he was getting the police as I was trying to run him over. He is completely MAD. I parked up and called Investec (as I had originally intended to do) to check on the payment status. All the time the MAD manager is screaming abuse at me. I am a 54 year old woman and found the behaviour extremely threatening. I will never go to this service station again. The bill is paid. I have all of the documentary evidence if you wish to see """
