Carrefour advertising

Hello community!

I need your advice.

I bought a house a few years ago, but I’m still receiving monthly advertising from Carrefour addressed to the previous owner.

I tried contacting Carrefour customer service, but they say they can’t stop the mailings because doing so would violate the former owner’s privacy rights.

I asked ChatGPT, and it suggested putting the same envelope back into a bpost mailbox after crossing out the original barcode and writing a note by hand indicating that the recipient no longer lives at the address.

After several attemps... this just hasn't worked.

Aside from the obvious suggestion of asking that former owner to unsubscribe, does anyone have any other ideas?

Thanks and best regards!
