Brand approval/registration name already taken?

Hi all. Ive lodged a trademark for a specific name. I am about to open my amazon account and want to submit for brand approval first and then brand registery (people said to do in this order). But when I search for shop names the name is already taken. I assume the products also have the brand approval.

What can I do here? I have my trademark that will be approved as this other business is not on there. And they sell food whereas I have clothing. How do I know im going to be able to open a store with my brand? I feel like ive spent all this money to trademark for nothing when the brand is already taken.

PLEASE help!
