All I can suggest is that you chase the Tribunal Service again.
The Judge being unable to provide you with a SoR should be Good Cause to have the tribunal Decision overturned, so if they still do not respond within a reasonable timescale, say another month, then I would recommend that you request a UTT hearing on this basis.
