if cannot resolve here and need third part help then go for Tribunal.

That is the best way to resolve problems like this.

If buyer is so sure she got a fake unit or deserve a new set of NDS or got conned by TS then go tribunal.
If seller is so sure he did not do anything wrong or did not sell fake NDS then to report in tribunal and set a hearing date.

Let the tribunal decide who is right.
