Replacement at Repair Centre taking FOREVER!

I got my son a MoveTime Family watch on a Vodacom contract. After 2 months the device stopped reading the SIM card. I handed the watch in at a Vodacom Repair centre who then, after a few days, informed that they can't fix the watch but will order a replacement watch. It has not been almost almost a month and they still do not have a watch in stock for me. The Vodacom Repair shop does not have an ETA on when I will even get the new watch. Could it be another month? Another 6 months? A year? Nobody knows... Kind if pathetic for the "SA's Best Network"!!
