Credit write offs

<p>After the end of a contract period, instead of renewing the contract,I converted this to a pre-paid cell. To my dismay I note that Vodacom has cleared the rand value of airtime on this phone.</p> <p> </p> <p>Seeing that I have two other contracts running with Vodacom I expected that the credit balance be transferred to prepaid or at least transferred to one of the other contracts.</p> <p> </p> <p>At no time was I told that the credit on this phone would revert to Vodacom. </p> <p> </p> <p>After numerous calls to Vodacom I am unable to get a satisfactory answer.</p>
