I am a member of the VIP Group, so DS definitely hooks up with lower charges. I've done a couple of Walmart/Kohls/Wayfair refunds with him.
During this holiday season, he has been responding quickly and providing updates. It may take some time for refund, and we must be patient,
but at the very least, he provides an update on the refund status. I would recommend him, and if you want your refunds as soon as possible, join the VIP group.
