Incompetency at Engen

I purchased my car on 01 March 2018, on the morning of 04 March 2018, I went to fill up at Engen garage in KwaMagxaki, Port Elizabeth, little did I know that my day would be ruined by *********** staff. The attendant poured Diesel instead of petrol,this after confirming with me twice. The attendant, manager and the OWNER, all failed to resolve the matter swiftly. It took them 4 hours to empty my tank. What an inconvenience! I pray I never have to use this garage ever again!
