I filed a feedback ticket 10 days ago now - and still no response. How can I escalate this?

Hi @colinux Feedback eventually came back to me - but by that time I had filed a ticket at https://developer.apple.com/contact/ They got back to me more quickly, and asked for a lot of generic information. They still have yet to resolve the problem, but I heard today that it had been escalated to internal engineers... Fingers crossed!

For the benefit of readers of the future: Thankfully DTS were able to help, and pointed out how I was being silly: I hadn't appreciated that all apps using App Store get a receipt - so I added a refreshReceipt routine to make sure my development version got a receipt to match App Review; I was also only checking for the presence of a valid receipt - not looking inside it for the relevant productID. Schoolboy errors - hope this might help other noob devs!

Unfortunately not... grrrr My app has since been released - and still it has the wrong pricing. :-( Apple keep responding to say it's been forwarded to the relevant teams - but they never seem to update me or get it fixed...
