Tenorshare review: Computer software 1

Purchased an app from Tenorshare on 1/2/23. The software was supposed to recover files on an external device that wasn't showing a connection to my laptop any longer.
Worked with Apple and scoured the internet for help in trying to solve the issue and finally found this software that would recover lost or corrupted files on alternate devices.
Downloaded the app and ran it (it took over 15 hours) and when it finished, all it said was done. I clicked on the files it recovered and they all had zero bytes and when you tried to open anything, the files would not open.

I worked with Apple for several hours to see if they had a fix for my problem and they didn't. I finally reformatted the external drive, which meant I lost all my 6TB of files and started over. Once it was reformatted, the external drive showed up on my docking station.
I went back to the company on 1/11/23 and asked for a refund because the app didn't recover any of my files and they wouldn't give me a refund, saying that their refund policy states that if I can't show them any reason (screen shots, etc.) as to why it error out, they won't return my money.

First of all, there were no error messages and all the files it did show weren't documents, pictures, etc., and couldn't be opened. Second... there was no refund policy showing with the purchase I made, only a link to download the app along with a registration number.
I have since deleted the app from my laptop and also the "so called recovered files".
I purchased the app and paid for it using my American Express Card. American Express is refunding the money, but I also wanted to let the BBB know that this company isn't being very receptive to refunding for something that doesn't work.

Instead, they want to give me access to other apps and I don't want to work with this company because they aren't very customer oriented to issues that arrise with their product(s) that don't work.
