Removing .apk from Google Play or Developer Console

Question

So I made this test application and uploaded it to developer console, but because it was my first application it's package is named com.myfirstapp.program. now later I have made much better version of the same program and this time it is under proper package name, however google play wont let me upload my new program because package name is different. And I really dont want to use com.myfirstapp.program. Is there anything I can do? I tried searching if I could delete my apk entirely but found out it is impossible, so I am kind of stuck here.
