False Advertising on Cell Sim Cards

FNB does false advertising on their cell sim card month to month contract. They advertise you can phone all numbers but do not disclose when they sell it to you that you cannot phone any numbers that are entertainment related such as DSTV, they also just say it is unlimited calls with fair usage and only after you have the number then 2 days later you get an sms that you must have at least 5% of incoming calls and use 100mb of data
