IEC and GSTIN issue

Hi members here,

I've been shown with this below dialogue even though I updated my valid IEC and GSTIN. How to contact eBay to inform the changes I've made?

You can't list, as you need to update your GSTIN and IEC on eBay. GSTIN and IEC are mandatory for sellers who are registered in India to sell on eBay.

To sell on eBay, provide your GSTIN and IEC on your My eBay Account Settings Profile page.
