Long painful refund, weak support.
The refund was eventually processed, but the overall support experience was very slow and frustrating. After waiting about 2.5 days for the seller to respond (which is reasonable), I escalated the case to G2G. It then took 5 days just to get a reply requesting proof, followed by another 5 days to resolve the case and issue the refund. G2G did resolve the case correctly in the end, but the lack of responsiveness and long delays significantly hurt the experience. I wouldn't recommend the site.
