Breach of contract by Vodacom

On a Smart Top Up contract. Vodacom decides yesterday to remove my minutes allocation and my call is cut on important call. Now have to buy airtime to make a call back. Phone Vodacom and advised my allocation of minutes was removed in error. It has now a new day and I am using airtime that I have had to buy. No urgency in getting this resolved while I pay a ripped of fee per minute because on their inability to stick to an agreement. Yes a contract, which Vodacom has now breached by removing my allocated minutes. Pathetic.
