Hi guys, I am sorry we were not active in this thread.
I won't be able to reply to all of your messages from the beginning, but I'll do my best to follow up from now on.  We do care about our customers and their security, but I am really not sure how can I prove it to you. What I can do is ask my colleagues to take a look at your tickets, case by case. In my experience, all of them are resolved after all the information has been provided.
Let me check what is missing for each of your cases and how can we fix it together. Please let me know your tickets numbers and I will reply one by one.
