Seller limit frustration

I have great feedback (100%) but hadn't used eBay for a while as I have been a caregiver to my parents for over 4.5 years.  My parents have now passed and it's time to sell a lot of their goods, however eBay is only allowing me to sell 1 thing a month, for $10 or less.  This is ridiculous - what can I do?  I have tried requesting a limit increase, have tried ringing them, and have also tried emailing.  I am at my witt's end, I want to get this done so we can move on.  Thank you for your help
