Complaint escalation guide
Can you complain to Ofcom about Tesco Mobile? Not for individual disputes: Ofcom sets the rules for the sector but does not resolve personal complaints or award compensation. Complain to Tesco Mobile directly first and keep written records, then escalate to Communications Ombudsman (Ombudsman Services) if it stays unresolved after 8 weeks or you receive a deadlock or final-response letter.
Which ombudsman handles Tesco Mobile complaints? Communications Ombudsman (Ombudsman Services). Once Tesco Mobile’s own complaints process is exhausted (after 8 weeks or a deadlock letter), you can take your complaint there for free. Go to the ombudsman. Read our Communications Ombudsman (Ombudsman Services) guide.
