Worst customer support team I've experienced in a long time. I've been trying to have the simple issue of switching my gamertag to another account however they cannot seem to fix the issue. I've had 4 cases opened and 2 closed even though the problem wasn't fixed. Customer support barely speaks english. What ever happened to the days of quality customer service? Wish they cared more about the customers rather than profit.
