As stated in the TOS, to which you agreed upon subscription, a user can cancel their subscription at any time during their membership; there are NO penalties at all. However, there are no refunds for partially used subscriptions, monthly or yearly. Again, users MUST cancel their own accounts and have the ability to do so easily on https://qello.com/. An email from the user saying he/she wants to cancel is not sufficient and the request will not be honored.
We do not offer refunds for users whom had signed up for a 7-day trial and had not cancelled within the allotted (7 day period) time.
