Hi Preferanon
It's normal DWP response, just let things move along at their own pace. At some stage you may get a phone call with an offer, if you do and it is not to your expectation, you can argue your case.
We have heard of this happening on the forum.
No HMCTS, cannot refuse an appeal unless it is out of time.
Good luck
Gary
