We created a QR code and printed it on hundreds of products. Then our QR code disappeared from the system. When I asked customer service if they could restore it because it is causing us a lot of damage, they said they were aware of the problem and would let me know when it was fixed. That's all. They didn't care at all about our loss due to their software not working.
This is not the first time I haven't found customer service useful and just wasted my time with it, just like with the program, which often doesn't work the way it should.
The management should be replaced very quickly, otherwise the company will go bankrupt...
