Poor Service

I will never use an Engen Service station ever again. One of your service stations in Port Elizabeth in New Brighton has the worst poor service ever. I went to buy there stood in a queue, whereas some people just come in without standing in any queue and they get helped. I enquired about this to the lady her name is Ntombi. She arrogantly told me the guy asked for a "favour". A day later I called and complained to the manager who promised she will get back to me. Clearly nothing has happened. I've been waiting since Tuesday. Clearly Engen doesn't mind losing a client. Worst part I fiil up my car at that station, because its merely 150m from my house. I will go to other services stations clearly they don't need my money. I will never ever use an Engen Service station ever in my life. I bet even this complaint won't be taken seriously....
