Help! Product compliance repeatedly rejected

I’m a new seller, trying to sell private label baby products on Amazon FBA. My listing has been inactive for over a month now, because Amazon keeps rejecting my compliance forms. It says there is “missing/inaccurate information on CPC”, but I have made multiple changes and updates and resubmitted many times, each time getting rejected. I don’t want my inventory to be thrown out because I haven’t made a sale yet. Should I hire a third party company to fix this for me, or is there an easier way? I have put so much time and effort into creating my business and I’ve been so close for so long, I’m trying not to feel discouraged. What should I do? Any advice is welcome.
