Isn't it my money?

I have tried to transfer an amount to another phone without any success.<br> There is enough funds available (R955.00), I have decided to contact the call center for confirmation.<br> <br> The agent confirmed that the amount cannot be transferred, now that is unfair practice...<br> Whether it's used to browse the internet, calling an unknown person in Iceland or transferring airtime.<br> I'm paying a monthly amount and surely allowed to do with it as I see fit?
