Deadline at a glance
8 weeks from receipt of the bill
§ 67 TKG
Complaints about the billing must be raised within 8 weeks of receipt of the bill — after that, the provider may treat the bill as accepted.
It is an AI, not a person: nobody looks at your individual case, and we do not know who signs up or for what reason. That is why we give pointers, but no legal advice on the individual case. Guidelines and playbooks in the platform are only guardrails: the AI relies on the available sources and your information. AI can make mistakes — check important results, and if in doubt, ask a lawyer.
What we pay special attention to
Curated from real cases. The AI review flags exactly these points in your document.
The 8-week deadline is often missed because it is shorter than for many other complaints.
With an automatic contract renewal, the objection period is often missed.
Without an itemized bill, disputed items can hardly be proven.
What you can do here in 5 minutes
If there are discrepancies in your phone or internet bill, you can request an itemized bill (Einzelverbindungsnachweis) (§ 66 TKG) and dispute the billing within 8 weeks of receipt (§ 67 TKG). If that does not resolve the matter, the free telecommunications conciliation body of the Federal Network Agency (Bundesnetzagentur) can help (§ 68 TKG).
Upload the bill — we identify disputed items and prepare the complaint together with an application for conciliation.

- Fine noticeAccused of a regulatory offense? At 2 weeks, the objection period is considerably shorter than for most other official decisions.
- Check T&C clausesExclusion of liability, notice period, automatic contract renewal — not every clause in standard terms and conditions is valid.
- Health insurer refusesTherapy, medical aid or rehabilitation refused? Often the insurer has missed its own response deadline — in which case the benefit is already deemed approved.
- Care level objectionThe long-term care insurer almost always follows the assessment of the Medical Service — if you object, you should check it module by module.
