8.ta more is a *****

I am currently using 8.ta more and have been enjoying the benefits of \buy one get one free\" (buy R5 get R5 free)<br> to maximize my benefit today I decided to buy R100 airtime knowing i will get R100 free and then use my R100 to buy 100 all network minutes at R90. great plan until I realized that when I make calls, they come off my minutes and not off the free R100 airtime.the free airtime expires on the 7th March but I cannot use it until I deplete my minutes.<br> <br> I mean it does not make sense to me to say you can only buy minutes after I have finished my free airtime, if I can do it then, why cant i do it now?"
