Petrol **** (Engen Randburg garage)

I'm really disappointed with Engen garage Randburg. Yesterday I poured petrol at engen garage in randburg. A guy called Romeo was the petrol attendant who was assisting me. After driving a few kilometers i noticed that the guy didn't put petrol in my car. This morning i went to speak with Lefata who is the manager there he said he was going to call me, he called me to tell me that the guy did put petrol in my car yet he didn't. yesterday i had to put petrol twice just because of that and he is covering for the guy saying he did put petrol. I'm so disappointed and angry
