TGF simcard doesn't support premium SMSes

I recently bought a TFG connect simcard and noticed I cannot send Smses to premium numbers. I called this morning only to be told that I cannot send Smses to premium numbers as the simcard doesn't support this. Why wasn't this disclosed!!? I bought this simcard to vote with it for a certain competition and now I can't and have R300 worth of airtime that I won't need anymore. WHY WAS THIS NOT DISCLOSED!!? WHY IS THIS HIDDEN FROM CUSTOMERS?? I'm sooo appalled by this!
