Waiting for hours and no support

Took an airport extreme to iStore Menlyn for repair. Only one service agent in a lengthy chat with two customers. After enquiring if somebody can assist I was informed I must be glad if somebody does assist because I need an appointment. Eventually another technician disapeared just to inform me that the Core group can not repair the airport extreme because it is out of 1 year warranty although I was willing to pay. How on earth do you sell an R7000 item with no after service support. The Core group leaves a bad apple taste in my mouth. I can now throw my R7000 investment away.
