It is too bad that NW does not take them off the list of partners. What will it take? They obviously have failed their end of any contract that may be in place with NW.
To let WorldPerks customers experience this kind of frustration over and over is crazy.
I did not use shop4 as a partner, but I guarantee you that I would have written BBBonline.org by now. Some of you may think they don't accomplish much, but I have had things resolved very fast that way.
