When a German telecom provider misses an agreed appointment for service or installation, the customer can claim compensation. Section 58 of the Telecommunications Act sets it at 10 euros or 20 percent of the monthly fee for each missed appointment, whichever is higher. The customer gets nothing if he caused the missed appointment himself. The same section covers faults. If the provider cannot fix a fault within one calendar day of the report, it must tell the customer so by the following day at the latest.
