MTN REWARDING UNUSABLE ARTIME TO PAY-AS-YOU-GO CUS

I purchased airtime from MTN yesterday (22 April 2015) on my mobile number *** and was rewarded with free MTN Airtime. The message I received from MTN141 read as follows: \Y'ello MTN has rewarded your recharge with R3000 FREE Airtime valid for 7 days"and for the second purchase I received a second message also from MTN141: \""Y'ello MTN has rewarded your recharge with R600 FREE Airtime valid for 3 days\"".<br> <br> 1. What MTN does NOT divulge to their customers is that that airtime can ONLY be used to call other MTN numbers.<br> <br> 2. MTN also does NOT divulge that this Airtime can ONLY be used within the Republic of South Africa.<br> <br> I am outside of SA at present and cannot use a R3"
