They have serious comprehension problems with the yamaha racing team

We’ve been trying to unsubscribe from the yamaha racing newsletter for weeks, but it doesn’t work.
On the one hand, the unsubscribe menu on their website does not work, and on the other hand, they have not been able to respond to several emails from the team.

We think yamaha racing officials are having a serious comprehension problem and therefore have failed to interpret our request.

But how is that certain GDPR law ?!
