Very bad service

I ordered new left front window for Kia Picanto on Thursday 21 January 2015. I kept on phoning to ask if my window has arrived. Every time I get through to Call Centre, even if you phone Centurion branch. If!! I get through to Centurion branch they kept on telling me she will check and phone me back. No one ever phone back. Saturday I went there to enquire regarding my window. The lady at reception said my window is there and I can bring my car Monday afternoon 2pm. I arrived there and the lady even told me where to park. After an hour, while I was sitting there, the lady comes to me and tell me that she must tell me my window did not arrive - after I was sitting there for an hour!!!! They then ordered another window - it is now Thursday and no feedback or response or call from them. I refuse to call again.
