****** Airtime

Just upgraded my contract on 6 October. 9 days later I run out of airtime. On querying this I am told that the new call minutes only come into effect at the end of the month and that I forfeit all benefits on my old contract. So I pay for calls for the whole month on my old contract, these are then taken away but not loaded on my new contract till the end of the month. I now sit with no airtime, although I was charged for it. Surely this is not honest and ethical
