Is the WP Hive test accurate?

My client has this problem:

Farazfrank created a demo online to be run by my client, but that demo includes Layout 13, which is only available in Slider Factory Pro. The free version, Slider Factory, ends with Layout 12.
This means that my client has no chance to test the received demo unless he buys the pro version up front.
We have both suggested FRANK to make the Pro version available for a test period, but apparently such an obvious service is impossible, and for unexplained reasons.
So, the customer in general is forced to buy what could be ‘the cat in the bag’ before he/she is able to confirm a demo from FRANK with a Pro layout (13 in this case) claiming to solve a Pro-problem.
Even the claim above ‘there is no error or issue’ is unsupported, as the customer is forced to purchase the Pro plugin to find out. If the claim shows to be wrong, he now has to deal with a web-company in India.
FRANK has chosen not to solve or even explain this Pro-dilemma.

FRANK: ‘We already gave the deal to test Pro plugin before buy’.

My client refutes that. He was initially given the offer to have the plugin installed on his test site by FRANK. But my client is interested in managing the installation himself while learning how the plugin works. For that purpose FRANK even produced a short screen copied video of the installation procedure to facilitate that.

Now, when my client asks for the Pro plugin to be available for his download, he has been ignored by FRANK, who just repeats the demand of doing the installation on behalf of my client.

At this point my client has had enough of FRANK, who keeps moving the post. We have stopped further consultations with FRANK.

This example is serving as a warning to others: Don’t buy the Pro plugin up front, wait until you know how it works.

My client has not asked for support from this location.
I repeat – My client has asked FRANK to provide a TEST version of the Pro plugin to be installed and tested by my client before a purchase.
This has proven to be impossible.
FRANK excuses the evasive behavior with ‘business matters’ and ‘WP.org guidelines’.

We have chosen not to do business with this Faraz, alias FRANK.
