In my case they sent me the same reason but then I found that it was because of the recent name change of PTU to IK Gujral PTU. I sent message on WES's twitter account and explained the reason they replied me withing a 24 hours and sorted it out.
May be after that they called university for clarification, and on my WES report they remarked the point that IK Gujral Uni was formerly known as PTU.
