poor service

I has a loyaty and my school card I do not understand why as a paying customer we as clients have to swipe our Woolworths and my school card. I left mine at the teller at the K90 shopping centre as the teller refused to swipe it. This has left a bad taste and would rather not shop at woolworths in the future. I sent woolworths a complaint and got a receipt that they would respond in a few days Its now well over a month and have had no response.
