BP ******* service

Zero stars is what I would rate this business. I have been coming to this BP for almost a year and I haven't had problems. I usually fill petrol and check my tyres and I did this today and I mentioned to the petrol attendant that he should give me R300 unleaded and he was filling my tank when I noticed that he put in more than R800. I then asked to speak to the manager who then allowed me to speak to the owner who blamed the entire incident on me and not on the attendant. I had to pay for something I didn't ask for and didn't even get an apology. You really need to train your staff. I will never go there and never advise anyone to go there.
