Dear Mustafa001 ,
I suggest you to give it one more week then you can send them an email in case your ecase does not chnage . I always refer to their PPR which is stated clearly " If you have not heared from us after six weeks, you may contact us using email from our website "
I will pray for you and inshallah you will have you ecase next week changed to DM. I know that waiting for 6 weeks without your PP is kind of stressing .
Do not give up hope and inshallah Allah will reward you for your patience .
Cheers . . . . . . . . . . .
Thanks my friend
