So I called UKBA just now (0870 606 7766), the operator initially said he won't be able to check anything until 14 weeks, then I said someone applied later already got result, finally he agreed to check it for me.
After inputting my details into the system, he told me there's nothing showing in system. I remembered at that time I applied for extention, the phone operator can see the status. Why ILR is so different as FLR?
Anyway, keep waiting, and keep fingers crossed.
