I think someone just misinterpreted something along the way.
I agree, this definitely looks like a miscommunication. They seem to be giving you advice about how to see the bitcoins in your "wallet" on your own computer (such as Bitcoin-Qt), on the assumption that you have withdrawn funds from MtGox and are complaining that the funds aren't visible in your "wallet".
I suspect what you are actually complaining about is that bitcoins were sent to your MtGox "account", and that the funds are not showing up in the MtGox "account" that should have received them.
Thank you, I was also under the impression that there was a lot of miscommunication. Problem was that I couldn't put it more clearly than in my initial support request. Maybe it's not clear about what wallet i'm talking about.
I'll give it another try. In my best Jappo-English...i'm Dutch...that's not easy
