Feedback on Galxboy review

I wrote a review about the level of service I had received at Galxboy while trying to do an exchange. A day later they reached out to me and sent the courier guy to collect the shoe and gave me a gift card.I am still waiting for my voucher. The quality of their product really top notch I would rather commend them if only they can work on their online refund/exchange portal,it really is letting them down big time
