Unallocated voucher payments on inactive cell no.s

When purchasing a Vodacom airtime voucher via FNB website, I incorrectly typed 1 digit incorrectly in the process. I take responsibility for my error. Knowing the I made the error, I tried calling the cell number...it appears that the number is not active.<br> I called Vodacom. I did not received any cooperation. hence this awareness.<br> My questions to Vodacom are:<br> If a cell number used in a airtime purchase is inactive, what happens to that payment amount which is unallocated due to the cell being inactive?<br> Does the Receiver of Revenue get involved?<br> Would be worrying if this money is moved into questionable coffers esp. when the cell number is inactive.<br> I would appreciate a response from a senior management Vodacom team member...<br>
