Since credits in my account were enough for me, I canceled the subscription, then all my credits were deleted. It was unreasonable. Because all the credits were paid, you DON'T have no right to delete it. What's worse, there is no after-sale service.
Hey there! Subscription credits are valid as long as you have a paid subscription, and we make sure to note this when subscribing and canceling your subscription. We apologize for any inconvenience this caused! Reach out to us if you have any other concerns!
