Does Corel even care about their customers???

I purchased the upgrade for X8 on February 27, 2017. Shortly after, Corel 2017 was released and I was presented with an option to upgrade for $199, this would make my upgrade $320. I sent a message to customer support and it remained unanswered. Few days later I contacted them by chat, I explained that I was rather upset about this issue and he replied that I could just turn off the notification so I would not see it, REALLY???? Obviously, he was missing the point. He opened a ticket and I was told that I would be contacted within 24 hours, again no reply. I sent a message to Corel again, and guess what, yep, no reply. Soo looks like they do not give a crap about their customers, at less me. Corel, milking your customers is a BAD idea. Fool me once, but it will never happen again, you are not the only vector solution in the market…think Adobe.
