I purchased 2 Xbox ultimate game passes as a Christmas present for my sons. Put the codes in and they were both region locked on a global key. Contacted CD keys who told me to try again and to contact Microsoft. I tried again, same result, contacted Microsoft and they tested the codes and said both were deactivated and to contact the seller. I contacted CD Keys who just just said that they could not help and refused to refund or replace. I did not accept this reply as it’s a faulty product that they have sold me. Contacted CD keys again on Twitter, Facebook and via email support. No reply, no help whatsoever, just ignored. £55 and a Christmas present down the drain!
