I managed to speak to Abdulwahap today on his mobile number, and he later replied by emial. I told him that there were a number of people keen to contact him and that he should check his email more frequently. He apologised for not staying in touch as he does not have internet access when visiting his home village.
Also he said that he will be away for the next 13 days or so on a guided trip to Umruqi. So guys, do drop him an email and be patient.
Also I got an email reply from John Hu, the other tour guide located within the same hotel.
Hope this helps,
