I threw in petrol at this garage and asked attendant to put air in my tyres. Asked him to put in a certain amount and he did the opposite. Causing a bubble in my tyre which forced me to purchase a new tyre which cost quite a penny. I then asked the owner of the BP garage to contact me. Which he did however to say the least the owner spoke to me like he was in authority and already made up his mind about the story. There was no apology. No customer services. Nothing from his side.instead he was talking about truck and taxi tyres. This to me is not acceptable at all and want to make it known to other drivers that should this happen to your vehicle be aware of this owner and his garage.
