*****ING WHAT I PAID FOR !!!

I upgraded my contract two weeks ago, with a shock I discovered today that all my Free minutes which I accumulated to the date of upgrade, has been cleared, and I now am paying for additional minutes which should have come from my free minutes, which I already paid for!<br> <br> Phoning the call centre, I was told that this should have been explained to me when I did the upgrade... which is NOT the case, but even if it was, this is wrong as Vodacom is *****ING my minutes which I paid for by means of a monthly subscription !!!<br> <br> How can you guys just take which does not belong to you? Definitely *****ing!
