Not happy with your 50+ mobiel subscription, the service, or an invoice? Below you'll find how to file a complaint, what you can expect, and what your next steps are if you can't resolve it together.

First, file your complaint with 50+ mobiel directly

50+ mobiel has a separate email address for complaints: klacht@50plusmobiel.nl. Describe as concretely as possible what happened, include your customer or phone number, and state what resolution you'd like to see. If you'd rather have direct contact, you can also call 088 228 2288 during regular opening hours and mention that it concerns a complaint.

What can you expect after filing a complaint?

50+ mobiel doesn't publish a specific maximum response time for complaints on its website. So feel free to explicitly ask about an expected response time when you file your complaint, and keep a copy of your message as proof of the date you filed it.

Not getting anywhere with 50+ mobiel?

Submit your complaint in writing first (email is preferable, since it gives you a paper trail) and, if the first response doesn't satisfy you, explicitly ask for a second review or to be referred to a supervisor. Many disputes still get resolved at that level.

Independent dispute resolution

If you genuinely can't resolve it internally, an independent dispute resolution body exists for the Dutch telecom sector that consumers with an unresolved complaint can turn to. Whether 50+ mobiel is specifically affiliated with this body isn't clearly stated on its own website — so check with customer service itself before filing a dispute, or check 50+ mobiel's latest terms and conditions on this point.

Common reasons for a complaint

Complaints about telecom providers usually fall into one of these categories: an unexpectedly high invoice, an outage that takes too long to fix, a subscription that wasn't cancelled as agreed, or a gap between what was promised when signing up and what you actually get (for example, internet speed or coverage). If you know which category your complaint falls under, mention it right away in your first message — that saves back-and-forth with customer service.

Tips for getting your complaint resolved faster

  • Be specific: state dates, amounts, and exactly what went wrong, rather than a general complaint.
  • Add evidence: screenshots of invoices, earlier correspondence, or app notifications back up your case.
  • Name your desired resolution: a refund, correction, or other action — that makes it easier for customer service to respond quickly.
  • Stay factual: a clear, matter-of-fact complaint is usually picked up faster and handled better than an emotional one.
