I have since my first review advised NSI that one of their members is charging customers contrary to a new law. Zero response. So their thorough checks don’t pick up changes to the law and they apparently don’t advise members accordingly. Totally worthless being a member.

NSI don't appear to investigate complaints thoroughly

I recently contacted NSI with regards to a complaint against one of there gold star awarded companies.

The impression NSI left me with, was one of, they don't investigate complaints thoroughly.

My complaint could of potentially resulted in lost of life, therefore, I was expecting NSI to leave no stone un turned.
