incorrect product sold

<p>My husband went to pick n pay clothing new markert in alberton to buy unlimited cellc data but was instead sold unlimited calls.</p> <p>the recepit of the product doesnt state whether its data or calls,only when he got home to recharge he realises that they have sold him an incorrect product. upon his return he was told that his already used the voucher and cannot be refunded at who's fault? as if that was not enough he had security throw him out for refusing to leave because they didnt want to refund him for a mistake that the cashier made by the name of Nompumelelo Moloi</p>
