Mo'nice option

I am not happy with my Mo'nice options, I've been with Telkom for over 5 years, and I've seen people who gets good Mo'nice options, they get 15g, for a R30 which lasts them for 30 days and all I'm getting is 4 gig for R57 whixh lasts for 10days and that's not fair, I would like this option to be looked at
