Why no ebucks any longer?

I have been informed that I will not be earning ebucks on my FNB credit card any longer, but will instead get free airtime. I can, however, earn ebucks if I upgrade to a more expensive credit card.<br> <br> Airtime is really of no use to me, as I have a contract on my cellphone. I have tried to dial into the number given to \claim"my free airtime without success. I have tried to transfer the free airtime to somebody with a pre-paid cell to no avail.<br> <br> I would really prefer to get ebucks"
