Voucher ****

So I upgraded my wife's phone in-store (Vodacom Blue Route ) to a Samsung Flip, all went smoothly till the R3000 voucher had to be redeemed from Samsung, several visits to the store, dealing with Rodney the instore Samsung brand ambassador nothing has been resolved as from the 10th of December. Last i spoke to the arrogant store manager, who felt that only Samsung was to blame and his store was devoid of any responsibility,I was promised by him the issue would be resolved by the 4th of Jan, he would personally speak Massmood, Rodneys Manager, still nothing one month later - is voucher real?
