Shopify Marketplace Connect

Worst customer service.
A representitive name Noel lied and tried to gaslight me.

We chose to do a price increase on Amazon in order to offset the Amazon fees. The app published the products in the original Shopify price. When I contacted customer service, they said tha the price the app sent was correct.
I send them screenshot showing that the price was wrong.
He wrote "One thing for sure is that the App sends the information/details to your Amazon Seller Central with the correct Prices. "
That was a LIE as the screenshot shows it did not.
