VirVentures VirVentures ordered through Walmart.com Did not disclose height restriction on equipment and refuse to refund Internet

We ordered the "Lumex LF1600 Stand Assist" from VirVentures through Walmart.com to help an elderly man with standing so we could maneuver him back and forth to the bed from his chair.  No where in the description did it state there was a height restriction. 

We received the equipment and put it together and within 10 minutes we found out it would not work and that he was falling through it.  Even the therapist said it would not work even using a gait belt. 

We immediately boxed it back up and got it ready to ship back. 

I contacted VirVentures, Scott Travis, to get a return authorization.  He replied back stating that they could not accept items that have been used.  He also stated that if the product was not used that they would charge me a 20% restocking fee.  Well, 20% of $472.00 is 94.40.  He further stated that if his company felt that the equipment was used, they would refuse receipt of the equipment and it would be returned to me.  

When I replied back and told him that it was not used more than 10 minutes and that it was back in the original packaging without any damage whatsoever, Scott Travis replied back and then told me I had missed the return window of 30 days from the receipt of the product.  It was not 30 days.  We received it on February 21, 2018 and I contacted him on March 22, 2018.  I still had 2 days before the 30 day window because February only has 28 days. 

I have come to the conclusion that no matter what, VirVentures will not refund the money. 

Now we are stuck with a huge piece of equipment that we cannot use.  Had VirVentures disclosed that there was a height restriction on the Lumex LF1600 Stand Assist, we would have never purchased it.  I feel they did this intentionally. 

Furthermore, I am disappointed that Walmart would allow VirVentures to treat their customers in this manner.
