I received my S4 6 weeks ago and been using this to communicate on the forum and when I say communicate I MEAN in the true sense of the word! So on the 1st of this month MTN deducted R4 754, my lady is the accountant in our business so she brings this mistake to my attention, yesterday I phone MTN to query the billing... turns out I used 2.5 gigs of data in 1month (all forum) my 1st 750 megs are free then R2 per meg thereafter. Needless to say GROOT K@K! Coming from a bill of around R1500 per month. So I now take the 5th (silence) peace in the forum.
