No, that never happened. Sometimes there were delays of 1-2 days, but nothing more than that

Wow, that's cool!

Once their support didn't respond to my chat either, but to be fair, it only happened once, and if I remember correctly, it was on Sunday. As I understand, it seems like on weekends and holidays, they have significantly fewer operators than on weekdays and they probably can't keep up with the large volume of chats. Otherwise, I would rate their support at 4 out of 5, no more.
