i'm pretty sure when the app store first opened, problems similar to this one were around, but i had thought they had been solved. this time though there's a twist. anyhow, i opened the app store and found some apps had upgrades. so i took a look and found two apps needed upgrades. i upgraded one and saw an app i don't recall buying. i clicked on it anyway and got this that is not my email address and i am the only user of this mac. i went to apple support and reported this. they replied with a case number and that they were going to loo into it. today i get an email from apple support telling me to call applecare and report this to them, and that a fee may be assessed. all i want to do is alert them to a bug in the app store and they want to charge me for it. has anyone else seen this behaviour in the app store? were they able to fix it?
