I don't necessarily know who is in the wrong of that but it does tell me that PTRs do not garantee quality
Usually player surveys asking what kind of content they like doing can fix that problem. PTRs may not guarantee quality, but there are measures that can be taken on both sides that can increase the odds of it being there.
