used airtime sold to customers

<p>tonight at 20h30 I bought airtime from the total garage in Winchester hills on xavier road it turned out the teller gave me airtime that was used already but was printed out the time I purchased it when I phoned the service provider they told me it was used by a other number in the morning,so now I have to ride my dam petrol out again to go change the voucher I recorded the call and I got my slips so this is how total robs the consumers I'm very disgusted in total fuel customer service. its my money and I'm the customer !!!!</p>
