It's worthwhile to mention that a bug report is one specific thing, whereas a request for support is a completely different thing. So, when discussing whether or not one's 'bug reports' were addressed properly, we have to talk about terminology.
A bug report, in most circumstances, is a one-way communication, i.e., the user submits a report that they found a problem, and technicians then fix that problem at an undetermined future time. The user doesn't wait around to see the results of their bug report, nor should they ever really expect direct communication on it. A bug report is you dropping off a note that you saw something go wrong, and then proceeding on your way. Therefore, it's important to realize that when one submits bug reports, expecting further communication on the issue will only serve to frustrate you. One-way-communication.
A support request differs, in that you are requesting a personal response and personal attention to your issue. Some things can be reasonably requested from support, e.g., "I can't log in." Some requests are unreasonable, though, ("This tree is clipping through this wall in this one part of a dungeon, and I want someone to come and fix it.") ... and those sorts of requests become bug reports, which is where the communication ends and the user goes about their business.
So. If you are indeed putting in Bug Reports and expecting responses, I'm afraid you've been misled as to how the system works. You don't get answers from bug reports. You wait to read the next patch notes to see if your report has been addressed.
On the other hand, if you're putting in support requests, for reasonable things that support can help you with, then you should be getting responses. Maybe there's an issue with how the requests are being submitted.
As others have mentioned, without knowing exactly what you need, and what kind of requests you've made (bug report vs. ticket for support), then we can't really help you one way or the other.
