\Free airtime"is a rip-off"""

On 17 February 2015 I received the following SMS from MTN:\ Y'ello! Recharge now & get 5X your recharge value FREE.. Airtime valid for 7 days. Offer valid till 24/02/2015 T&C's."<br> <br> This is a rip-off as they are intentionally hiding behind the T&C's which thy intentionally do not state in their SMS as I found out later when I did recharge for R180 and obtained the so-called \""free airtime\"" of R900. For the following week I used my phone more often than usual to find out on 25 February that I had only about R141 left of my normal airtime whereas it should have been at the very least more than R180. I therefore went to one of MTN's agency in a shopping centre whose identity I am not willing to divulge for good reasons you will see. There they explained to me about the hidden T&C's: \""The free airtime only comes into play once you have used up your R180 normal airtime and the free calls are also only valid for MTN to MTN number calls!\""<br> <br> Hiding behind the T&C's is a deliberate rip-off.! When I stated this to an MTN employee in the said agency"
