Shell Garage Monclair

What a waste of my time!! We got to the garage at 8am to only fill up R50 worth of petrol, the attendant named Sonto clearly was not paying attention. She filled up R1000 worth of petrol, furthermore she denied not listening , blaming it on us, that we were not paying attention while she was filling and had the audacity to say that it's our fault. They made us wait here for a very long time saying that the mechanic was on the way. No one was paying tension to us, that attendant just left us in the vehicle and took the keys with her, after a while we decided to find it what is going on, I am late for work and this is taking forever!.. not happy with the service and definitely not happy with the attendant, she clearly doesn't know how to do her job.
