Return Policy on slip says nothing about card

I bought a pair of jeans at Markham Vangate , it was late and i was the last customer . I was told that i cannot fit my them because they closing the store. I then bought the jeans and told the that i will just return if they not fitting nice. <br> <br> I fitted and they did not fit nice so I sent my wife to return them at Mitchell's Plain store where she got told by the Manager Evelyn Alexander that the policy requires the card to be available before they could refund her,as I have used my debit card when buying. She asked to speak to the customer service as the slip mentioned nothing about bringing the card used for refund she was not given the phone at the store. <br> <br> She called *** customer service spoke to Khanyisa at around 15:15pm on 3/6/2015. Khanyisa confirmed the card needs to be available before refund. When she was asked of the area managers contact Khanyisa did not know and asked my wife to walk back to the store to get Area Manager's contact. So much for someone that works for customer service not to have the contact of the Area Manager??<br> <br> Why is the slip not mentioning card for refunds ? I feel this is misleading
