I have not gotten my lost credit back yet.
Be aware!!! You should write down and record your credit before you log out.
Credits are going away overnight.
Check out your transaction record. You've got all the details there. It has never occurred to me anyways. You can always contact CS as well if you have any questions. GL
Similar to Simon, that has never happened to me. And I've never heard anyone else report it happening to them either. At this point, we have an N of 1.
