Get bookings done for ur rukhsati in the coming months or over christmas hols asap and show them that..like hall bookings and dress bookings and all.. just to give the VO an idea that if u are unable to travel now, u will definitely do it very soon and yes u ideally should do it very very soon since ur eligibility is being questioned by a VO on the grounds of no rukhsati....please think thru it and plan thru it.. usually when ppl get these emails they rush to a rukhsati or begin to plan one asap.. and i think u shud do the same although im sure its easier said than done..
Also, attach a letter from ur work place with them rejecting your leaves. that will be a good proof to the VO that ur leaves are not sanctioned genuinely these days..
U should send them the remaining proof of ur visits immediately...call logs, fb statuses/checkins, chats, skype logs,boarding passes, photos..
May Allah ease ur process and help u
