how exactly do MTN work PayG charges because i thought that if you bought airtime and then converted them into data bundles then you had x number of MB to use, when i phone 141 and listen toi my remaining MB the voice on the phone says i have x number of MB's remaining on my 1GB bundle and R499 will be deducted from my airtime credit for my subscribed 1GB bundle on the 30th September but i dont have a contract on this line, i would like to throw this card away if i so wish, please can someone clarify the billing process and will they deduct R499 from my credit card on said date?
