Doctorkhan said:I dont understand whats going on these .... a request letter was sent to my wife by the end of march but she didnt receive it yet .
I am not the only one who is facing this prob .... a few other members also didn`t receive their letters .... i have already emailed them abt it 4-6 times but they are not responding . They have already checked with the postman and the post office .... i m suspecting this could be an intentional delay otherwise why would a bunch of ppl would lost their letters . Considering scenario , i would suggest everyone to plz write them and enquire abt ur case , cuz u never knw when would they request u something and time would pass ( especially those that have the same timeline as mine ).
