Well, I received a number of replies when I contacted a ninja but my request was not acted on: Vodafone stopped providing an email service a few years ago but offered customers the option of having a Forward put on the address, which I did. Big mistake! Mid-2018 I started getting all sorts of spam, and threatening emails. I emailed a ninja and was told the address would be deleted. At least 3 months later, it still exists! And I still get spam etc. Sigh.
What's the point of having so-called ninjas if they cannot do anything! I am no longer in NZ so making contact is difficult.
