Thanks for sharing your experience. People don't actually realise that even if you have very few bugs and errors in your product but your customer service is terrible, then your product is bound to fail because people won't let anyone treat them bad and are likely to reject that product with such attitude.
I have been working in customer service for quite some time and know from experience that people will endure most of the errors, bugs and faults, as long as you let them know they are valued and appreciated. As long as you keep praising customers and doing them favours, they will recommend your product and be happy because they were treated well.
