Poor service

Im so dissapointed at engine diepkloof zone 5 service station on the 8th I drove there to fill up my diesel car with diesel fuel, however the attendant put petrol in my car I logged a query with them and they advised they'll attend to the matter they took my car and advised they fix the problem. This is so bad that even when I call them they promise to come back to me and they dont on the 14th I was supposed to meet with manager Reymond and that wasn't successful, on the 16/08/21 I made a call spoke to Jerry and he promised to call me back after 15 min to provide feedback but that didnt happen im so dissapointed I can't even believe the way im so inconvenienced.
