Hi <br> <br> i have 3 numbers linked to my account with mtn and i have had billing issues with EACH of them<br> 2 numbers i have a top up account and i was being charged for this AIRG service ( i have ever heard of or given consent to ) every week and it used up all my air time they could not help me unsubcribe and happiery have AIRG access to keep charging me with out my perission<br> <br> my tab account i had an open account to which it never came up to more then R200 a month ad i have wifi at home and i was signed on to get 500mb free last month my account was over R3000 ad thismonth already over R2000 which they just debited my account , when i questioned this they just said i must of used it but they will send me a report as i deputed it they also confirmed i did have a limit on my account of R1000 but since my account was a open account they would not stop me from incurring charges over my limit (hence the over R7000 account for a month and a half when i norm use R200 only!!!!!!) i still have not got a report for these huge bills and they only solution mtn gave me was to charge my ipad account to a top up account so it will never get this high again !!! i want answers NOW i am still waiting!!!
