We were told though by company representatives, that the game was staying intact. So my argument to this statement is that we were tricked into spending real money by false statements by the company.
Well, consider that Zynga is the company who abruptly laid off 20% of their workforce with no prior warning, I'd say that you should be aware that not everyone in the company actually knows what the business plans are. It's highly likely that the customer support staff first learned the game would be shut down at the same time you did.
