They don’t have support line, not sure about the social media if they’re gonna reply you quick but the best way is to create support ticket ( Although, it takes 1-3 days to get a respond, working days only )
This is so frustrating, why they are doing this, i encountered same error since several months ago and still didn’t find any clue what is this. even after purchasing they showing this error, Tried everything but back to square one.
