ASA All,
I have arrived in Lahore on 24th Oct 2017 and searched hard to find this service. It is 29th Oct 2017 and I manged to speak with a representative on one of the numbers given in Urdu add. Very sadly, this service has been discontinued and Red Buses replaced it, he confirmed.
I am very sad to learn this as many of my family and friends confirmed that this service was brilliant and they throughly enjoyed it.
May Allah SWT protect Pakistan's good services and features Ameen Ya-Rabb!!!
