BAD, BADDES, WORST SERVICE I'VE EVER ENCOUNTERED

I booked in my device to it to be checked what might be the problem with it as it does not pick up any cellular network only to a shocking discovery that MTN does not repair iphones they only replace which they demanded a fee of R12 000 because my warranty just faded out with just 4 months. I wonder if they did even assess the device or they just wanted to milk money out of me. MTN IS A ****.
