Unreliable

<p>I Loaded R60 airtime this morning at 10:25 and just tried to make a call at 11:33 and got the message, "insiffucient airtime to make a call". This is an ongoing problem since i joined MTN, and makes me think to rather switch to Vodacom where i never had any problems. If you load airtime, due to being in an emergency situation, you can't rely on MTN that you can call for help. This is unacceptable</p>
