Shell service station Dlamini

I went to shell service station in dlamini Soweto and I always fuel my car there and then as I had to use their v. Power plus card to redeem my points the attendant told me he cannot do it as I know he could and he left me there and he told me someone else will help me I was so disappointed as it's where I get good service but this petrol attendant was so disrespectful and he seemd lto care less about clients and he had bad attitude towards me.
