Question: why announce after 4 months that you're going to announce something in a few days? Couldn't you wait a few more days and just announce it without pre-announcing whatever it is you'll come up with?
That is exactly my point. I think there was no need for the supposed rush to make the announcement when they have kept mute for how many months long yet coming to make promise whose fulfilment might take another frustrated customer to open up a reminder thread here quoting this same thread in wait for the payment.
I think it would have been better to wait a little more and then coming out with this apology thread alongside immediate refund plan. Don't just keep your reputation dragging all the way because it is not easy getting it back.
