Pay for Vodacom mistake

I upgraded my contracts from Clearwater mall and was told that my new contracts will commence on the 1st Feb 2016 as I was changing packages. The one contract commenced today correctly, however my other contract somehow commenced on the 31st Jan. I realised this in the evening on the 31st and when I called 111 to query this they said there is nothing they can do and I must contact ***, Tholakele from the upgrade department said I must go to the branch bese there is nothing that they can do. I then called 111 again, to be told that there is nothing they can do because I used the airtime. <br> My contract is suppose to commence on the 1st Feb as per our agreement and the contractt that I signed, not on the 31st. I signed both contracts on the same day and one was done correctly and the other one not. <br> <br> can this be sorted urgently and give me my airtime as per the agreement. I do not have a new contract that commenced on the 31st Jan 2016.
