In his blog, Scott Adams describes his exasperating experience following a change of motherboards. Central to the story is the fact that he has two phone numbers for Windows re-activation, both of which claim they are an official Microsoft call center and that the other is a scam. Neither are any help anyway. Seems to be a topical issue right now.

That's the two guard, two door problem and the solution is well known [stackexchange.com] partly because it appeared in the film Labyrinth [wikipedia.org].

Except that it isn't. The people on the false hotline are not obsessive liars, they are fraudsters who will say whatever supports their fraud. If for a given question the truth supports their fraud, they will tell you the truth.

It doesn't matter if a party lies consistently because you only have to craft questions to expose them and the structure of such questioning is well known and allows for the possibility of dealing with two rogue parties [wikipedia.org]. Admittedly, it is a secondary consideration when you're contacting such parties because you have one or more technical faults but it is possible.

From the linked Wikipedia article (emphasis by me):
Which directly contradicts your claim
Indeed, a fraudster constructs a fiction and tells you the truth about that fiction with the only lie being the claim that this fiction were the reality. And the only ways to catch fraudsters is to either detect a contradiction to reality, or get them beyond the borders of their ability to consistently maintain their fiction, so they get into self-contradiction.
