Mtn advertises their mtn100 anytime package as, R100 airtime and 25 sms's every month. I have two of those. 1 with mtn service provider, the other with altech. The one with altech actually gives me what they say, but the one with MTN service provider only gives me R86 airtime. Their excuse is that vat is being subtracted from the airtime. They must be the only company in the world that does it that way...
