It is true indeed that the Sandpit can be an unforgiving place. There has been a thread on here for many years dealing with these issues. They have always been there and always will be there. Perhaps it would have been wise for you and others to read them and/or consult others before committing to joining NAPT. If you signed the contract for the attraction of the tax-free money then simply accept that and put up with the ****. Otherwise leave. You have no sympathy from me and I suspect many others who have been there before.
Act in haste - repent at leisure my friend.
