Engine cover - horrible experience

I recently took my car in for a service and the following day I opened my car in front to fill the water tank as mine is leaking and they did not have in stock to replace it when I realised that my engine cover was missing. So I went back to them to ask and the response I received was beyond shocking as I was dismissed like a silly little child who didn't know what she was talking about, and was told that all polo vivo's come without an engine cover. So I left confused but then decide to call my brother who I knew that he would know better that me whether there was a cover or not, needless to say that he confirmed that mine had... not suprising as it was I also decided to ask my 14yr old daughter because since the tank was leaking I would normally have her with me when we refill the water tank, and she also said it had a cover. I am super disappointed, especially by the manner in which my matter was addressed by the staff of Lindsay Asker Welkom with no intrest of hearing me out or probing any further to really understand me as a customer.... and what is worse is that I also went to a friend's who has the same car as mine and hers has the engine cover like mine did BUT I was told something along the lines of "all polo vivo's come without an engine cover"
