Is Getting Expert Help a 'Cheat' or a Necessity for Psychology Dissertations?

I'm feeling incredibly conflicted. I'm struggling with the methodology section of my Psych PhD dissertation it's complex, and I'm worried I've misinterpreted some statistical tests. My confidence is shot. I keep seeing ads for a Psychology Dissertation Writing Service that claim they can offer expert consultation and help refine specific, tricky chapters. My question is: is using a service like this generally accepted when you're genuinely stuck, or does the academic community view it as essentially outsourcing the work? What are your thoughts on this fine line?
