Appalling service from TFG and Markham Woodlands

If I could give this negative stars I would. I made a purchase at Markham Woodlands using my TFG card and used the voucher in order to get a discount. I took the clothes and tried them on at home only to find that they were too small so I returned them to the store. When I try to return them I was told that it’s causing an issue because of the voucher I used. They try to solve for that by creating a gift voucher of the same value but they deducted this gift voucher from my account (so at this point I had paid twice for one thing) I never received the SMS with the gift voucher so this solution failed. I then requested that they just reverse the transaction back into my account along with the gift card and I left the clothes at the store. The lady assured me that she would do that but she never did. I had to return weeks later only to find that nothing was actioned. I called the call center myself in order to get this resolved but this was just the beginning of my nightmare. I was told by multiple consultants that the money had been reversed only to find that they were referring to the gift voucher. They kept logging tickets that would be resolved but they were all focusing on the gift voucher reversal instead of the actual purchase being reversed. I have spoken to God knows how many consultants including a team leader and my issue has still not been resolved even though every ticket they log has been resolved. The latest ticket CS-*** which was logged by a team leader has seen the same fate. It’s been resolved but I still have not received my money back.
