Day light roberry

I went to sasol at crn Visagie and Potgieter street on sunday the 05th at 20h39,i was helped by a guy called Charles.I had petrol in my car and bought petrol for R200,after the guy was done the petrol did not go up at all.I told the attendants at the garage then they said it might go up while i am driving such incidents do happen.I drove a block away but it was still the same then i went back.We had a long argument with the guys about the issue but it was never resolved.I went there again on monday morning on my way to work to complain about it but still the matter was not resolved i was only told that the petrol was there even though my kilo's where going down and the gauge is also going down.How do you pour petrol and not see it?my car is still new.This is day light roberry and i feel that the garage is not taking this matter serious.I am going to share my story on social media and 702 radio for people to know how they are being ****** at sasol.
