Council tax Tribunal appeal failed. What next?

Sorry I did miss your reply.
The VOA didn't provide a massive amount of evidence. He could only find 2 houses of equivalent banding. These houses were a similar size and design, equivalent bedrooms, similar area providing similar amenities. They were built in 1996 and therefore also weren't built before 1991. Prior to these 2 houses been built there was no evidence of any other equivalent houses in the area and therefore they were difficult to band. They were handed E and never challenged.
There has since been many houses built in the area of very similar design, size and close to amenities. They have all been banded D. This was our evidence. We found these houses were equivalent in every way and could be considered to be located in a more desirable location.
The only other evidence from the VOA was the housing markets within the area and how his 2 properties were within the banding of E if you take these into account. However other market trends show that this could be incorrect as they band his evidence in D. This was our counter argument and both pieces of evidence were deemed inconclusive. This was also evidenced using 2 independent online calculators which both agreed with our findings. I understand that this isn't taken as strong evidence in a VT.
So to sum up the VT the housing market trends was deemed inconclusive as we both submitted strong arguments for both D and E banding. We provided a strong case for many houses that are in band D and are of a equivalent price, design, size and location. In my eyes the evidence on the day is the only evidence that should be used.
However the decision and all the evidence was overridden entirely by the VOAs experience of market trends.
