I agree with copperdog here. The rocket pack and GTN for your ship were the two big ticket items to work for. While, if you know the "ins and outs" of what sells on the GTN, credits are hardly a big deal a lot of folks did work hard to unlock these perks by running countless dailies. Basically giving it away for a relatively small amount of CCs is bad customer service in my opinion... Not that I have any expectation EA will give a damn, let alone reimburse any players their credits back.
No, they won't. And they shouldn't have to, this is a stupid thing to complain about and I have no idea why anyone bothers or cares. Sure, it's a large amount of credits. But who really gives a ****?
