Did you talk to Mr. Jahangir? He never said me anything like 'no need to remind'. Rather he always felt sorry for not receiving all my calls as he was busy. Anyway, you can go to IOM office in person and talk to him. When I went there to collect my tickets I did not had any prior appointment but he gave me about 45 minutes and we discussed many things including personal information.
Another thing, whenever I talked to him during our initial introductory periods I always used to give UROY's name as reference. And Jahangir bhai always recognized him. After UROY's departure he even told me one day, "Dr. Uttam has left on ......." So I don't see any problem mentioning anyone's name while contacting with him but choice is yours. It should not matter as they are committed to giving you this service whether you have heard from any person or from website. I think your problem will be ended soon, have a little more patience.
