MP's office sends email to London/Islamabad.
Person who receive that email check status of that case in system.
What status he finds in system write back to MP.
MP reads same email back to applicant on phone or write on email.
So, MP does not care what response he gets from embassy he just pass on......that is funny part.
Some time it interpret the response on the basis of date of application receipt and current timeline of that embassy....that is worse funny part.
so, MP relay on systems reply........which is not reliable most of the time.
Because it do not see what visa officer is doing on that case.
Also does E-CASE help anyone correctly during whole processing........so.......same system.
