I'm looking for a way to contact the company here. I've been trying to get a refund for two months, but no one returns my emails. Does anyone know how to contact them?
contact with the Developer's support apartment
Contact who? You haven't said who the developer is.
However, this is a technical support forum for developers, not for end users. You would get much better responses if you posted in the Apple Support Community.
However, even there, you'll need to provide more information. What developer is this? What app is this? Please don't just say the name of the app. App names are 100% meaningless. You must provide a link to the app.
Also, where did you buy the app? Did you buy it from an Apple App Store? Or from somewhere else? You should have your receipt and it will clearly say that.
I can tell you have developers respond to e-mails 100% of the time. Even if they don't respond, that's a meaningful response. It means they don't care, they've gone out of business, or they've just abandoned that app. This is very common.
