Short answer
Mobile contract complaint enquiries should identify the provider, tariff, handset or SIM agreement, complaint issue, bills, price changes, service problems, cancellation or switching steps, provider response and ADR stage. Legal4U cannot decide whether a provider breached contract or regulation.

Collect Contract, Bill And Service Records
