I am wondering what is the best way to report a bug.
We are having an issue and I submitted a case and Salesforce keep closing it, with their generic close response,
"Please be informed that Developer support is currently available only to our premier customers and Premier partners ...."

I have posted this question on StackExchange regarding the bug
http://salesforce.stackexchange.com/questions/70187/low-code-coverage-when-production-and-new-test-class-to-deploy-are-over-80?noredirect=1#comment91714_70187

but to summarize it seems that the code coverage in our production org is displaying the wrong numbers, as all of them past and the overall is above 80%, when validation 1 test class that will increase a class coverage from 0% to 100% it fails saying that code coverga is only 73%
how can this be possible if the new test class will improve the coverage. The only thing that I can think is that the initial overal coverage is wrong and it is not 82%
