From your conversation i got my answer why escrow.ms and one more user is not leaving trust for the trade done b/w us because it will add me into default trust which is not fine for now.
Leaving trust feedback on your profile and adding you to their trust list are different. Leaving feedback does not add you to their trust list.
My guess is that they are in defaukt trust list and hence, they don't want to change your trust score.
