I recently started working as a self-employed person in a secondary occupation and I received an unsolicited letter from SDZ for a membership contribution of 190 euros. Is this membership required? I am already a member of Xerius.
After some Googling, I came across this article:
“Misleading letter” href=”https://www.nieuwsblad.be/cnt/dmf20240411_96484583″>https://www.nieuwsblad.be/cnt/dmf20240411_96484583
How is it legal to send unsolicited invoices?
