This is something all should know as it impacts all players.
The terms&conditions that the publisher of this game (Zynga, or I shall say Take Two Interactive now that they bought that company) uses to justify their refusal to allow refunds within 14 days even in the case of blatant cases, like the Gargoyles downgrading immediately after release, infringe our customer rights under EU law.
You may want to read this first:
Note that the refund can be requested without any justification. In the instance of the Gargoyle nerfing there was actually a very concrete justification as the products sold (the heroes) were changed from what initially advertised and paid for by the customers.
Also note that the exception to the 14-day rule about streaming of films and other media does not apply here either as that was meant to safeguard products that would lose their value once downloaded (for example you could watch a film and ask a refund thus unfairly benefiting of the whole value of the product). In this case the downloaded products (the heroes) have little immediate value as they need to be upgraded for future use, thus you do not benefit at al by asking them to be returned/refunded.
I did exactly so, received the refund from Apple and then was unfairly punished by the publishers who set my account to a massive (-33k) negative balance, far exceeding in any case the value of the refunded purchase. Not satisfied with that, they have now threatened to close my account if I do not clear the balance within 13 days. Tried to reason with their support but it is like talking with a brick wall.
Zynga hides behind their T&C and the usual mantra that they need to intervene to balance the game. That is ok if something over time stops behaving as expected, but for a new product to be changed within a week is totally unacceptable. Other publishers offer new products for free for a limited time to test their impact in the game, before removing them and do the adjustments prior to actual paid-for release. That is the correct practice and that way no one can feel cheated.
I will probably be (unfairly) kicked out soon after being a loyal paying customer for over 4 years. I feel cheated and disgusted, but if everyone stood up to defend their rights these things would not happen.
