Very bad service

on the 19 October 2018 , 9:40, I went to the station to fill up my tank with R100 petrol (5.9L) 93 unleaded. I was assisted by the gentleman by the name of Mpho. I always put R100 petrol from Engen and I know I will drive for up to 65km. to my surprise the petrol, that day it could not even get to 25 km. My car suddenly stopped and I had to park on the side of the road and ask for assistance and only to find out that there is no fuel. The guy who happen to stop and help me drove to the nearest filling station to get me another petrol since it was finished. I thought there was something wrong with my car but the guy just realize that there is no fuel. I didn't think the problem was the fuel since I just had R100 filled up.

There was so much inconvenience because I was even late for my interview. When I get to my work place, I have phoned the garage to complain about the service as this was unusual and the lady looked at the footage and saw my car but the camera cant reach the pump. The lady promised to investigate the matter and call me back on Monday. I had no phone call on Monday, I then gave them a benefit of a doubt and give them some time. I lost my patience and call again on Friday 26 October. The lady told me that I was on the phone and it was my responsibility to check if the fuel was filled correctly. so my question was "just because I didn't look at the tank, does that give them the right to do whatever that they want with my fuel". I didn't take that responsibility because I trusted them so much, and Engen is the only garage that I fill in my tank in. I'm very disappointed with the service that I got from the garage and I think even though it will be difficult for me to change the filling station, I guess I have no other choice but to change it to people who will give me a good service.
