MTN Sim and data deal.

I was recently given the opportunity to market MTN sim deals on behalf of Telcorp. we sold over a 100 of these sim cards which was supposed to provide the client with 40g night surfing and 20g day surfing. we had several client complaining that the sim was inactive. and we were promised that these sims are pre-activated and ready for use. we also had one client who used the sim for a day and then it was disabled. this seems like a problem on the side of Telcorp and not MTN. so all work has been suspended.
