Bank promotional cash

Hello, I'm confused. In 2021 I opened two checking accounts with two different banks and they both gave me around $300 in promotional cash.

 

One bank produced a 1099-INT for that amount but the other one did NOT produce it. When I asked, they told me that since it's a promotion, it would have qualified for a 1099-MISC (not INT) only if it was more than $600, so they do not produce any form.

 

Who is right and who is wrong and what should I do?

 

Thank you
