Streaming service Netflix is facing legal action in the Netherlands for putting up prices for viewers with a permanent subscription.

A mass claim foundation, Stichting Bescherming Consumentenbelang, says the company is acting illegally in changing the terms and conditions for subscribers without fully informing them. Subscription costs, the foundation says, have risen up to 75% since 2017 “without any transparency”.

The foundation says millions of Dutch consumers are affected by the changes and puts total damages at €673 million. Efforts to mediate an out-of-court settlement failed, hence the resort to legal action.

Netflix said in a reaction that it takes consumer rights “very seriously” and that it is convinced its “terms and conditions are in line with local laws and consumer expectations.”

Netflix lost a similar case in Italy earlier this month, but has said it will appeal. A case is also underway in Germany, and in Austria, the company and consumers reached an out-of-court agreement on compensation.
