bad service

I went to factorie eastgate 2days ago and I wanted to refund my pants and I was asked to produce the card I bought with which happened to be a debit card and the cashier/supervisor insisted on putting it back in my debit card and I asked her doesn't that happen when you have used a credit card and she told me about her capital bank so I kept quiet gave her the card and I went to the bank today to check I even made a statement nothing was refunded so I called the shop and she told me ' I told you it would ttake up to 14 days to reverse ' I mean if I was told why would I risk bank charges and a statement?their service was bad and I paid with my debit card that was my money either way it doesn't matter if I get cash cause I paid for those pants
