Lose Your WRAG If You Appeal

I have just been to a tribunal last week for ESA and was awarded 18 points and placed into the WRAG Group.

I have read several posts on various different sites and it people say that you are allowed to appeal this and try and be placed into the support group.

However, all these posts say that, if you appeal the WRAG decision and you are NOT successful, there is also the chance that you may end up losing your WRAG and ESA. Is this true????
