Redeem the Saturn guarantee at Mediamarkt?

I have a case of damage to my laptop, but unfortunately I have to go to Würzburg for work. Since Würzburg does not have a Saturn, I wanted to ask whether it is necessary to submit the laptop to Mediamarkt about the guarantee because Mediamarkt and Saturn somehow belong together…

is that possible?

No do not go

No, that doesn't work, are different societies

No.

Just because they have a common "parent company" somewhere, there are still two companies that operate independently of each other.

But isn't it like the vouchers?

I don't know what about the vouchers, but you can't deduce anything different from them (here: exchange).
