2 x deductions 1 x pin ????

Yesterday 3 Aug purchased goods at Pick 'n Pay Noordheuwel Krugersdorp. Paid with my ABSA card, cheque account, but they put through twice. I only put my pin in once. How can this happen ? Where is my protection from ABSA ? Called ABSA, said wait 24 hours P 'n P should reverse. Called P 'n P this morning, no they can do nothing. Speak to your bank. R641-35 off my account twice and<br> nobody wants to give me my money back. Pathetic service from both ABSA and Pick 'n Pay.
