Bug in Himita Theme

I have downloaded Himita Shopify theme from Envato Elements and it has a bug as product pages are not loading properly. When I contacted the theme authors, they said themes purchased Envato elements does not provide technical assistance. Now they are asking money to remove the bug. What to do?

Author support is not available for items downloaded on Envato Elements. If you need support from this item’s author, You can take a look at this item on Envato Market. If support is offered, you will receive 6 months of support when you purchase the item there.

Thanks
