Not happy

I bought a bucket hat online, the order arrived and I went to the store to claim and return it because I had made a second order with two bucket hats. So I felt there as no need to have two black bucket hats. The counter lady said unfortunately we won't be able to give you back your money in cash but we can refund on the bank card you used, she processed to say if your card declares then we will refund you in cash and you won't have to wait for 48 hours to receive your cash. I agreed, she then processed and my bank card kept saying wrong pin, and I couldn't go to the bank because it had already closed( after 4pm) to fix my issue. I went to shoprite just see if my card really had an issue. I even took a video of it refusing my pin. Then I went back to truworths to explain that I am really in distress because I don't know what's wrong with my card. First of all if my card had rejected their transaction they would have gave me cash but when my pin refused they didn't say oooh let us just help you and give you cash. I ended up saying ok let me just exchange for something else, keep in mind i wanted a refund. I went to the fitting room tried on those 2-pack short shapers( tights like those short leggings) and I exchanged, they didn't give me a till slip they said its ok i can go with my oline inlvoice order slip. The following day I was like but I really wanted a refund let me go back and return this. I get there they say they can't help me because I don't have the other slip. I explain, they didn't give me. Some rude lady came there started telling me that yesterday your card was refusing and we told you to come back some other time. And I said I'm not fighting, and I don't like the way you are speaking me. I came here to collect my order and do a refund, you refused to give me cash even when my card was refusing to process. Then she said anyway these CAN NOT BE REFUNDED OR EXCHANGED!!! She just threw them there and went to call the manager. She explained what I couldn't even hear what she was saying, her words against mine. The manager came to me, instead of hearing my side and get the details of what happened she says unfortunately we can't refund these they are part of Underwear. First of all, no one gave me a slip or even said lady please note these can not be returned they are part of Underwear. No one said that, knowing fully well I wanted a REFUND initially, no where in theirs product information says tights are put of Underwear, you even allowed me to try it on. I said to them please print out the slip I was suppose to had received. The manager said "the person who helped you yesterday should have kept this online paper and gave you a slip" so for the inconvenience can we EXCHANGE these because we can't refund you. NOW they can exchange but they said they can't refund it due to hygiene reasons. I am done buying things at truworths. I was falling in love with their new fashion now I'm just so disappointed I'm nolonger interested. They can gladly take your money but when it's time to refund its a problem.
