Tread+Miller terrible quality worse service

I bought a pair of of boot and tread + miller on the 7th may. The boots were of such a low quality the sole came lose on the 27 July. Because the stitching was **** the sole was glued on. I tried returning the boots but the store told me up to 7 working days for a refund. I said I would accept a centre gift voucher cause I needed a replacement pair. They refused, I spoke with an area manager Cindy Franciscus whom continuously spoke over me and informed me that up to 7 working days for was the process and she was not willing to attempt to escalate the request. she said she would try to see if I could get a centre gift card for the next day but could not give be a guarantee. She was also condescending and made me feel like I was inconveniencing her. I then called client service to lodge a complaint and they told me it can actually take up to 14 working days not the 7 working days previously quoted and that it was unlikely any arrangement would be made for a gift card. Which means the area manager **** to me previously. I'm currently waiting for a call back that was promised for tomorrow morning. Don't shop at tread+miller the only thing worse than their quality is the way they treat their clients
