Bad service

On the 27th of April around 6pm, I went to Engen garage in Kriel (Mpumalanga) and the service was so shocking. I waited for 10 minutes without anyone attending to me. The petrol attendants guys were busy chatting with the cashier ladies. I went to one of them and asked if he could put some petrol in my car, he responded by saying that he was busy and I should wait. I asked to speak to the manager and the cashier ladies responded by saying that they was no manager on duty and they laughed at me together with the petrol attendants guys. Other cars came and they went and attended to them leaving me standing. I ended up leaving the garage without petrol in my car. It is so disgusting for a garage like Engen to have service like that. I was shocked of the service i got as this was my first time to vist Mpumalange and experience such a terrible and disgusting service. If thats the way Kriel Engen garage is treating people, it sucks a lot
